# How can the magnetic field produced around a current carrying be detected?

The magnetic field produced around a current carrying conductor be detected​ using a magnetic compass. If you place a magnetic compass near the apparatus that you have set, the needle ‘will’ deflect. The deflection of the needle is caused by the magnetic field around the current carrying conductor.

## How is the magnetic field around a wire related to the current?

When a current flows in a wire, it creates a circular magnetic field around the wire. This magnetic field can deflect the needle of a magnetic compass. The strength of the magnetic field is greater closer to the wire, and increases if the current increases.

## How is the strength of the magnetic field at a point near a straight conductor related to the strength of the electric current flowing in the conductor?

Answer. As a current flowing in the straight current conductor carrying wire increases it’s strength of magnetic field also increases. This means current flowing in the conductor is directly proportional to it’s strength of magnetic field.

## How will the strength of magnetic field at a point around a current carrying conductor change when?

The strength of magnetic field due to a current-carrying straight conductor is inversely proportional to the normal distance between the conductor and the point where magnetic field is to be determined. So as the point as moved away the strength of the magnatic field goes on decreasing.

## How can you generate induced current in the circuit?

The generation of an induced current when a conductor is placed in the region of changing magnetic field is called Electromagnetic Induction. The current will only induce in the conductor coil if the magnetic field around the coil changes. So either the coil or the magnet needs to move towards or away from each other.

If the distance between two magnets with like poles gets smaller, then the repelling force between them will get bigger, because the force between two magnets gets stronger as they get closer together, and weaker as they get farther apart.

## How does the magnetic field produced by a current carrying circular wire at a given point vary with current and number of turns of wire?

We know that the magnetic field produced by a current carrying wire at a given point depends directly on the current passing through it.

## Why is that if a current carrying coil?

Current in a circular loop produces the filed. If number of turns increases direction of the current will be same as that of the direction of the current in single turn. Hence, at the end the field due to each turn just adds up.

## Why does a compass needle get deflected when brought near a bar magnet?
