Question

A 75 cm straight wire moves straight up through a 0.53 T magnetic field with a velocity of 16 m/s. What is the induced emf in the wire? O 3.18 V O 6.36 v O 4.78 V O 12.3V

Answer 1

Answer:

6.36

Explanation:

If a 75 cm straight wire moves straight up through a 0.53 T magnetic field with a velocity of 16 m/s, the induced emf in the wire is 6.36.

Answer 2

Answer:

Induced emf of the wire is 6.36 Volts.

Explanation:

It is given that,

Length of the wire, l = 75 cm = 0.75 m

Magnetic field, B = 0.53 T

Velocity, v = 16 m/s

The wire is moving straight up in the magnetic field. So, an emf is induced in the wire. It is given by :

$\epsilon=Blv$

$\epsilon=0.53\ T\times 0.75\ m\times 16\ m/s$

$\epsilon=6.36\ V$

So, the induced emf of the wire is 6.36 V. Hence, the correct option is (b) "6.36 V".
