Scrapyards use massive electromagnets to lift entire cars. When the crane operator wants to drop the car, they simply cut the power, the magnetic field vanishes instantly, and the metal falls. 2. Maglev Trains

"Maglev" stands for magnetic levitation. These trains use powerful electromagnets to float above the tracks, eliminating friction. This allows them to reach speeds of over 300 mph (480 km/h) with a remarkably smooth ride. 3. Medical Imaging (MRI)

Most people think of magnets as the static clips on a refrigerator, but the world actually runs on a much more dynamic version: the . Unlike permanent magnets, which have a fixed magnetic field, electromagnets can be turned on and off, adjusted in strength, and even reversed with the flick of a switch. What is an Electromagnet?
A small electromagnet vibrates back and forth against a permanent magnet to create sound waves.
From the motor in your electric car to the massive cranes in scrapyards, electromagnets are the "invisible muscles" of modern technology. 0;ea;0;79;0;a3; What is an Electromagnet?
