Faraday's law of Electromagnetic induction

Question

A body enters in MRI machine in 10 sec. If the magnetic field is 1.5 T and circumference of MRI machine is 0.9 m then find out emf induced in the body.

Easy

A

0.96 V
B

9.6 V
C

9.6 mV
D

96 mV

Solution

$e_{av} = \frac{∆ ϕ}{∆ t} = \frac{{Bπr}^{2}}{∆ t}$
