Electromagnetism, Motors, and Generators

Front

What rotates inside a coil of wire in large generators to produce electric current?

Back

Magnets.

Front

What kind of field is often associated with electric fields?

Back

Magnetic Fields.

Front

What is the flow of energy through a motor?

Back

battery -> electrical current -> copper wire rotor -> magnet -> mechanical energy.

Front

What happens to the strength of an electromagnet as you add more coils?

Back

The strength of the electromagnet increases.

Front

What is electricity?

Back

Electricity is the flow of negatively charged particles called electrons.

Front

What is an electromagnet?

Back

A type of magnet in which the magnetic field is produced by an electric current.

Front

What is the role of a rotor in a motor?

Back

The rotor converts electrical energy into mechanical energy.

Front

What is the principle behind how generators work?

Back

Generators convert mechanical energy into electrical energy using electromagnetic induction.

Front

What is magnetic induction?

Back

The process by which a changing magnetic field creates an electric current.

Front

What is the relationship between electricity and magnetism?

Back

Electricity can create magnetic fields, and changing magnetic fields can induce electric currents.
