What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It consists of a coil of wire, often wrapped around a core of ferromagnetic material.

How can you increase the strength of an electromagnet?

Back

You can increase the strength of an electromagnet by winding the coils more closely, increasing the number of loops in the solenoid, or increasing the electric current.

What is electromagnetic induction?

Back

Electromagnetic induction is the process of generating an electric current in a conductor by changing the magnetic field around it.

What is the relationship between electricity and magnetism?

Back

Electricity and magnetism are interrelated; electric currents produce magnetic fields, and changing magnetic fields can induce electric currents.

What is the role of a core in an electromagnet?

Back

The core, often made of iron, enhances the magnetic field produced by the coil of wire.

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which components are connected end-to-end, so that the current flows through each component in turn.
