Question

A horizontal copper rod moves paralleľ to the
horizontal. Induced e.m.f developed across its ends
due to earth's magnetic field will be maximum at
(1) Equator
(2) Latitude 30°
(3) Latitude 60°
(4) Poles​

Answer 1

Answer:

At the poles.

Explanation:

The rod is moving in the horizontal direction. So it's have no effect due to Bh (Earth's horizontal Field) since angle is 0 and sin tetha is 0.

At poles Bh is 0 and Bv is maximum. So maximum emf is induced at the poles.
