Find the magnitude of the emf induced in the rod when it is moving toward the right with a speed 7.50 m/s.

3 volts

Explanation:

It is given that,

Magnetic field, B = 0.8 T

Length of a conducting rod, l = 50 cm = 0.5 m

Velocity of the conducting rod, v = 7.5 m/s

We need to find the magnitude of the emf induced in the rod when it is moving toward the right. When a rod is moved in a magnetic field, an emf is induced in it and it is given by :

Putting all the values,

So, the magnitude of the emf induced in the rod is 3 volts.
