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

6.36

Step-by-step 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

Induced emf of the wire is 6.36 Volts.

Step-by-step 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* 0.75\ m* 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".
