Question

A straight wire length 35 cm sweeps across a 0.94 T magnetic field with a speed of 2. 00 m/s. What is the maximum value of the electromotive force that can be induced in the wire?

Answer 1

Given that,

Length of a wire, l = 35 cm = 0.35 m

Magnetic field, B = 0.94 T

Speed, v = 2 m/s

To find,

The maximum value of the electromotive force that can be induced in the wire.

Solution,

The maximum value of the electromotive force that can be induced in the wire is given by :

$\epsilon=Blv\\\\\epsilon=0.94\times 0.35\times 2\\\\\epsilon=0.658\ V$

So, the maximum value of the electromotive force that can be induced in the wire is 0.658 V.
