Question

Factors affecting magnetic field of a circular current carrying conductor

Answer 1

1)The amount of current flowing through wire

If current is increased then deflection of needle of magnetic compass placed inside wire also increases.

Strength of magnetic field is directly proportional to current.

2)Radius of circular wire

Strength of magnetic field is inversely proportional to radius of circular wire.

The deflection of needle of magnetic compass placed at the centre of circular wire of smaller radius is more than that placed at centre of circular wire of larger radius.

3)Number of turns in circular wire

If number of turns in circular wire are increased,Magnetic field at the centre of loop increases.
