Note that the earth’s magnetic field also produces a flux through the
loop But it is a steady field (which does not change within the time
span of the experiment) and hence does not induce any emf Example 6 3
A circular coil of radius 10 cm, 500 turns and resistance 2 W is placed
with its plane perpendicular to the horizontal component of the earth’s
magnetic field
