A) current
B) radius
C) number of turns
D) area
Correct Answer: D
Solution :
The magnetic field at the centre of circular coil \[B=\frac{{{\mu }_{0}}nl}{2r}\] where r = radius of coil \[I=\] current flowing in the coil n = number of turns in a coil Therefore, magnetic field in a circular coil does not depend on area of coil.You need to login to perform this action.
