# in which direction will each compass point when there is a large current in the direction shown?

## In which direction will each compass point?

A compass points north because all magnets have two poles , a north pole and a south pole, and the north pole of one magnet is attracted to the south pole of another magnet. (You may have seen this demonstrated by a pair of simple bar magnets or refrigerator magnets pushed end to end.)

## Does a compass point in direction of current?

Since compasses work by pointing along magnetic field lines, this means that there must be a magnetic field near the wire through which the current is flowing. The magnetic field produced by an electric current is always oriented perpendicular to the direction of the current flow.

## How to find the direction of current using a compass?

The right hand rule is a trick for remembering the direction of a magnetic field generated by a current in a wire. The compass is showing you what direction the magnetic field is in, so you can use the right hand rule to work out whether the current is flowing north to south or south to north.

## How does a current affect a compass?

When a current runs through the wire, the compass needle is deflected, illustrating the magnetic effects of current flowing in a wire. … No deflection is observed if the compass needle is placed near to and at right angles to the current carrying wire.

## Why does compass point north?

The north pole of a compass magnet points toward the north. … Earth’s south magnetic pole is near Earth’s geographic north. Earth’s magnetic north pole is near Earth’s geographic south. That’s why the north pole of a compass points toward north because that’s where Earth’s south magnetic pole is located and they attract.

## Which direction would a compass point to if located right on the geometrical north or south pole?

The magnetic field is perpendicular at the poles and the magnetic needle of the compass tends to align with the magnetic field. Therefore the compass will get aligned in the vertical direction if is held vertically at the north pole.

## Which direction do compasses point when there is an electric current nearby?

When you put the compass near the electrical wire with current flowing through it, the compass did not point north; instead, the compass needle pointed in the direction of the current’s magnetic field.

## What is the direction of the current clockwise or counterclockwise?

Current flows counterclockwise in this circuit. Using the right hand rule for the conventional current in the wire, the right thumb is pointed along the wire pointing to the left at the top of the circuit.

## What direction will the compass needle point when the current in the wire is into the page?

The compass needle always points in the direction of the current in the wire. The compass needle always points in the direction of the magnetic field of the Earth (north), regardless of the magnetic field of the current in the wire.

## How do you find the direction of current?

The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.

## What direction do magnetic field lines point?

They point from the north pole to the south pole. However, the magnetic field lines do not just end at the tip of the magnet. They go right through it, so that inside the magnet the magnetic field points from the south pole to the north pole. Thus the magnetic field lines form a closed loop and do not have any ends.

## Which side of the coil does the north magnetic pole of the compass needle point to?

south pole
Compass needles line up with magnetic fields. Since Earth is a magnet, a compass will normally line up with Earth’s magnetic field. Because opposite magnetic poles attract, the magnetic north pole of the compass points toward the magnetic south pole of the Earth.

## How does the direction of the current in the loop compared to the electric field?

How does the direction of the current in the loop compare to the electric field? … Currents in wires are carried by moving electrons, which are negatively charged. Therefore, the electrons move in the opposite direction as the arrow on the wire.

## Why does a compass needle moves when placed near an electric current?

Every electric current produces magnetism. … Since the compass needle is also a magnet, the magnetic field around the wire attracted and repelled the ends of the compass magnet and caused it to move. You have seen that electricity flowing through a wire can cause a magnet to move. This is called the motor effect.

## Which type of electric current only flows in one direction?

direct current
In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction.

## Where does compass Point at North Pole?

If you mean the geographical North Pole, the needle would point south, as that is the only direction one can go from there; more specifically it would point south along the 112.4 degrees west longitude meridian towards the magnetic north pole at 82 degrees north, which is where compasses point.

## What direction does a compass point in the Southern Hemisphere?

To answer the original question compasses normally have the end that points north painted red, so even compasses for use in the Southern Hemisphere are marked to point North.

## What is compass north?

1. compass north – the direction in which a compass needle points. magnetic north, north. direction – the spatial relation between something and the course along which it points or moves; “he checked the direction and velocity of the wind”

## Which direction would a compass free move in a horizontal plane?

In which direction would a compass free to move in the vertical plane point to, if located right on the geomagnetic north or south pole? A compass is free to move in a horizontal plane, while, the earth’s field is exactly vertical at the magnetic poles. So the compass can point in any direction there.

## Which way would a compass needle point if you were at the magnetic south pole of the earth?

north pole
Bring the magnet near your compass. Opposites attract, so the north pole of your needle will point towards the south pole of your magnet.

## Why does my compass point south?

Reverse polarity is where the magnetism in the compass needle becomes permanently reversed so the red end of the needle points south instead of north. This is different to the magnetic needle being temporarily deviated a little when near a metal object or weak magnet and correcting itself as soon as it is moved away.

## When you are in the southern hemisphere does a compass point north or south chegg?

If brought to the southern hemisphere, the northward pointing needle of a compass will then point south.

## Why is north north and south south?

If you walk your compass around the electric wire the S->N direction is always that of the magnetic field, as defined by the right-hand rule. … According to some, the tradition of putting north up and south down dates back to Ptolemy. But there is a perfect symmetry between the north and south magnetic pole of the Earth.

## Is a counterclockwise current positive or negative?

Counterclockwise is the positive rotation direction and clockwise is the negative direction. For example, a torque that rotates an object counterclockwise is a positive torque (see figure 6 below).

## Is counterclockwise current positive?

Whether this is clockwise or counterclockwise depends on how the diagram is drawn. Oh, I answered that the current flows from positive(battery voltage) to positive (top plate of the capacitor) which is clockwise.

## How do compass needles find direction?

Q9) How is a compass used to find directions? … A compass has a magnetic needle that can rotate freely. When a compass is kept at a place, the magnetic needle aligns in a north-south direction. The red arrow of the compass needle is termed as the north pole and the other end as the south pole.

## In what direction will the compass needle point when the compass is placed in the magnetic field surrounding a wire?

Scientists believe that this field is produced by convection currents in the Earth’s core, which is made from iron and nickel. When a plotting compass is placed in the Earth’s magnetic field, the north pole of the compass will line up with the Earth’s magnetic field lines and point to magnetic south.

## What is the direction of needle in compass at neutral point?

Since the net magnetic field is zero at neutral points, the compass needle remains unaffected (i.e. it comes to rest pointing in any direction). In this way, it can be located.

## Which direction does DC current flow?

one direction
Current direction

Electrons flow from negative to positive. In a direct current (DC) circuit, current flows in one direction only, and one pole is always negative and the other pole is always positive.

## What direction does conventional current flow?

Conventional current flows from the positive terminal to the negative.

## Which direction does the current flow in a circuit?

Since electric current is a uniform flow of electrons, its direction is opposite to the flow of electrons. Therefore the direction of electric current in an electric circuit is from the positive terminal to the negative terminal of the battery.

## Do magnetic field lines go from north to south?

Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. … The earth spins around the geographic poles, but magnetic compasses point to the magnetic poles.

## In which direction do the magnetic field lines point near the south pole of a magnet chegg?

Magnetic field lines point away from the south pole of a magnet and towards the north pole of a magnet.
