Electromagnetic brake

An electromagnetic brake is a device that stops moving objects using magnets and electricity. It works by using magnets to attract metal and create a force that stops the moving object. This force of attraction is like a brake, so it’s like having an invisible brake that can stop things without touching them. It's like when you try to stick two magnets together and they resist moving away from each other. The electromagnetic brake creates this same force, but much stronger. Then electric currents being sent to the magnets cause them to rotate very quickly, creating a force that pulls the moving object to a stop.
