Electro magnets Flashcards
How is an electromagnet created?
An electromagnet is created when an electric current flows through the wire, which causes a magnetic field to be created around the wire.
What is a magnetic field?
A magnetic field is a region where magnetic materials experience a force.
What is an electromagnet?
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.
What can we do to make an electromagnet stronger?
To make an electromagnet stronger we can increase the number of coils or increase the current.
What happens when lines attract each other?
When lines attract each other, field lines lead from one magnet to the other.
Why is magnetism a non contact force?
magnetism is a non contact force because the materials involved don’t have to touch each other.
