Practicing Success
Magnetic braking in trains is an example of which of the following? |
Magnetic levitation Electromagnetic Induction Hysteresis Eddy Currents |
Eddy Currents |
Strong electromagnets are situated above the rails in some electrically powered trains. When the electromagnets are activated, the eddy currents induced in the rails oppose the motion of the train. As there are no mechanical linkages, the braking effect is smooth. |
