Answer:

electromagnet

its the answer

Answer 2

Electromagnets

Electromagnets are made up of an arrangement of wire coils, often ferromagnetic substance such as steel.

An Electromagnet is a temporary magnet unlike a bar magnet which is permanent.

• Electromagnets lose thier strength over time.
• The direction of the magnetic field lines of a electromagnet can be reversed by reversing the direction of the current.
• The magnitude of magnetic field inside the electromagnet is uniform everywhere.

Some Information :-

◉ Electromagnet is made by passing current through the coiled wires. If the direction of the current changes then the direction of the magnetic field lines also changes.

◉ A more high quality ferromagnetic metal can result in greater strength of the electromagnet.
