Question

What is the smallest time interval in which a 5.7 T magnetic field can be turned on or off if the induced emf around the patient's body must be kept to less than 0.12 V ?

Answer 1

The smallest time interval in which the magnetic field can be turned on or off to induced the emf is 47.5 s.

Emf induced in the coil

The emf induced in the coil is calculated as follows;

emf = dФ/dt

where;

• dФ is change in flux
• dt is change in time

0.12 = 5.7/dt

dt = 5.7/0.12

dt = 47.5 s

Thus, the smallest time interval in which the magnetic field can be turned on or off to induced the emf is 47.5 s.
