Question

How does the strength of the magnetic

field at the centre of a circular coil of a

wire depends on

(a) radius of the coil

(b) number of turns of the wire of the coil?​

Answer 1

Answer:

The magnetic field strength varies directly with the number of turns of wire. It increases as the number of turns increases. Answer: The magnetic field at the centre of a circular coil of a wire is inversely proportional to the radius of the coil whereas Directly proportional to the number of turns of wire in the coil.
