The magnetic field at the centre of a current carrying circular loop of radius R, is B1.
The magnetic field at the centre of a current carrying circular loop of radius R, is B1. The magnetic field at a point on its axis at a distance R from the center of the loop is B2. Then the ratio (B1/B2) is :
(a) 2√2
(b) 1/√2
(c) √2
(d) 2
