Question

factor affecting magnetic field of a circular current carrying conductor​

Answer 1

Explanation:

Factors on which magnetic field produced at centre of acurrent carrying circular wire depends are:

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.
