What uses an electric magnet?

Answer 1

No. Electromagnets are usually made of a core (some type of metal that can be magnetized such as iron) and a coil. The coil is put around the core, and if current flows through the coil the core will become magnetic.

Answer 2

Magnetism is the property of attraction possessed by magnets.

Any object that posses a magnetic field is magnetic.

An electromagnet is a device consisting of an iron or steel core that is magnetized by electric current in a coil that surrounds it.

...so, yes. Electromagnets use magnetism.

Answer 3

Magnetism is what makes a standard electric motor work.

DC electrical motors contain large curved permanent magnets, between which coils of wire are wrapped around frames called armatures. When current flows through the wires of the coil, it creates an electromagnetic field. It is the interaction between this created field and the existing magnetic field that causes the motor to turn, as the coil is attracted or repelled by the permanent magnets.

In other motors, interacting fields are created between a fixed part of the motor (stator) and the rotating coil (rotator) in much the same fashion.

Answer 4

An electric magnet is commonly used in various applications such as electric motors, MRI machines, speakers, and magnetic separation devices. It works by creating a magnetic field when an electric current passes through it, allowing for control and manipulation of magnetic forces.
