An electromagnet is a fascinating device that uses electricity to create a magnetic field. It's like a temporary magnet that you can switch on and off with the flick of a switch.
Basic structure:
Imagine a coil of wire wrapped around a core made of iron or another ferromagnetic material like steel.
When you pass an electric current through the wire, it creates a magnetic field around each loop of the coil.
These individual magnetic fields add up and become concentrated inside the core, making it behave like a powerful magnet.
