At a place earth's magnetic field,

5 \times 10^5 \mathrm{~Wb} / \mathrm{m}^2

is acting perpendicular to a coil of radius

R=5 \mathrm{~cm}

. If

\mu_0 / 4 \pi=10^{-7}

, then how much current is induced in circular loop?

Options

A $0.2 \mathrm{~A}$
B $0 \mathrm{~A}$
C $4 \mathrm{~A}$
D $40 \mathrm{~A}$ .

Correct answer

B. $0 \mathrm{~A}$

Step-by-step solution

As the earth's magnetic field is acting perpendicular to the coil and as here is no charge of magnetic flux through the coil, the current induced in the coil is zero.
