What do you call a magnet created by passing an electric current through a wire coil?

The term for a magnet created by passing an electric current through a wire coil is an electromagnet. When an electric current flows through the wire coil, a magnetic field is generated around it. This principle is based on electromagnetism, which connects electricity and magnetism. The strength of the magnetic field can be altered by changing the amount of current flowing through the wire or by increasing the number of coils. Electromagnets are widely used in various applications, including electric motors, transformers, and magnetic resonance imaging (MRI) machines, due to their ability to be turned on and off and to have their strength adjusted.

Permanent magnets, in contrast, maintain a constant magnetic field without the need for an electrical current. Bar magnets are a specific shape of permanent magnets, and magnetite is a naturally occurring mineral and a type of iron ore that is magnetic but does not require an electric current to exhibit its magnetic properties.
