Imagine a circular loop contained in the plane of this screen. suppose that a straight current-carrying wire that is perpendicular to this screen passes through the center of the loop. if the current in the wire were to be increased by a factor of 4, the strength of the magnetic on the loop will increase 4 times

magnetic field due to an infinitely straight current-carrying wire = B1 =

mu0 * I / 2πr

if current in the wire were to be increased by a factor of 4

B2 = mu0 * (4I) / 2πr

B2 = 4 B1

The strength of the magnetic on the loop will increase 4 times
