Question

Will a circular loop of bigger radius produce a stronger magnetic field than a smaller loop, if
the same amount of current passes through both the coils. Explain?

Answer 1

Answer:

Actually no, by computing with Biot Savart' s Law, the magnetic field on the axis of a ring comes out to be inversely proportional to the radius of the loop, which means for same current passing through both the coils, the coil with smaller radius will produce a larger magnetic field.
