An electromagnet is a magnet whose magnetic field is created when electricity is flowing.
What is an electromagnet?
A device consisting of an iron or steel core that is magnetized by electric current in a coil that surrounds it.
What is magnetic field?
Magnetic force is defined as the space surrounding a magnet in which magnetic force is exerted.
What is electricity?
A form of energy created by charged or moving electrons or protons.
What does it mean when electricity is flowing?
The movement of energy is called a flow. The flow of electricity through a wire can be thought of as being similar to the flow of water through a pipe. Electricity usually flows in specially protected wires, but it can also move around using many other objects.
How does a magnetic field and the flow of electricity relate?
The electromagnetic force produces two related phenomena: electricity and magnetism. They combine to generate electromagnetism. A magnetic field is created by a moving electric charge. Electric charge movement is induced by a magnetic field, resulting in an electric current.
What produces a magnetic field?
Electric charges in motion. Charged particles in motion have both an electric field and magnetic field associated with them.
How does an electromagnet work?
An electric current flows through a coil of wire. This produces a magnetic field in the wire. The sides of the coil that carry current at 90 degrees to the magnetic field experience a force as they interact with the magnetic field.
