Eddy currents are a fascinating phenomenon that occurs when a changing magnetic field interacts with a conductor. A great real-life example of eddy currents is found in brake systems on trains and some cars.
When a train applies its brakes, electromagnets are activated near the wheels.
These electromagnets produce a changing magnetic field that induces eddy currents in the wheels, which are made of conductive metal.
The eddy currents create a magnetic field that opposes the original magnetic field, effectively slowing the wheels down.
This braking system is called eddy current braking and is highly effective in slowing down heavy vehicles like trains. It is a crucial component of the braking system for trains and other vehicles, contributing to safety and efficiency.
