The working of magnetic braking of trains is based on

Options

  1. AAlternating current
  2. BEddy current
  3. CSteady current
  4. DPulsating current

Correct answer

B. Eddy current

Step-by-step 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.
