Ever wondered what is an electromagnet? An electromagnet is a device that produces a magnetic field by applying an electric current. Unlike permanent magnets, which retain their magnetic properties without external influence, electromagnets require an electric current to generate a magnetic field. This magnetic field can be manipulated by varying the strength of the current or changing the number of turns in the wire coil. Electromagnets find widespread use in various applications, from powering electric motors and lifting heavy objects in industrial settings to enabling technologies like MRI machines in the field of medicine. The ability to control and adjust the magnetic strength of electromagnets makes them versatile tools across numerous industries.
