What is an electromagnet? 🔊
An electromagnet is a type of magnet in which the magnetic field is generated by an electric current. It consists of a coil of wire, often wrapped around a ferromagnetic core, which enhances its magnetic properties when current flows through the wire. Electromagnets can be turned on and off, making them extremely useful in various applications, such as motors, transformers, and magnetic resonance imaging (MRI)
