Question

A screwdriver is being used in a 13.5 T magnetic field. what maximum emf can be induced in V along its 10.5 cm length when it moves through the field at 0.85 m/s?

Answer 1

EMF = 1.20 V

Step-by-step explanation:

It is given that,

Magnetic field used by the screwdriver, B = 13.5 T

Length of screwdriver, l = 10.5 cm = 0.105 m

Speed with which it is moving. v = 0.85 m/s

We need to find the maximum EMF induced in the screwdriver. It is given by :

`\epsilon=BLv`

`\epsilon=13.5\ T * 0.105\ m * 0.85\ m/s`

`\epsilon=1.20\ V`

So, the maximum emf of the screwdriver is 1.20 V. Hence, this is the required solution.
