How Can Eddy Currents Brake a Train Without Contact?
š” The Answer
- Eddy currents are induced in conductive rails by moving magnets on the train.
- These currents create opposing magnetic fields that slow the train electromagnetically.
- The braking force is smooth, quiet, and does not rely on friction.
- Eddy current brakes are used in high-speed trains and roller coasters.
