Q156 / 180 · KCET 2017 · Physics

The working of magnetic braking of trains is based on

A
Alternating current
Correct answer
B
Eddy current
C
Steady current
D
Pulsating current

Solution

The working of magnetic braking of trains is based on Eddycurrents. Eddy current is induced in conductors by
changingmagnetic fields. They circulate in closed loops perpendicular to the plane of magnetic field.

Hence, the correct answer is option: 'B'.
