The earth’s magnetic field (B_E) at the equator is horizontal, uniform and points north – south. A conducting square loop of side l and resistance R is kept in the vertical plane with two of its sides pointing east-west direction. This loop is moved in east direction with a velocity v. The current induced in the loop is

Solution

The correct option is A $z e r o$
Magnetic flux linked with the coil is not changing. So $Δ ϕ = 0.$ So, net emf induced is zero. Thus, the current is zero.
