Electromagnetism, Motors, and Generators

Front

What type of energy is produced by a generator?

Back

Electrical energy.

Front

How does adding more coils around an electromagnet affect its strength?

Back

The strength of the electromagnet increases.

Front

What is the energy conversion process in generators?

Back

Mechanical energy is converted to electrical energy.

Front

What is the process of generating current in a conductor called?

Back

Electromagnetic induction.

Front

Describe the flow of energy through a motor.

Back

Battery → electrical current → copper wire rotor → magnet → mechanical energy.

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 principle behind electromagnetic induction?

Back

A changing magnetic field within a coil of wire induces an electromotive force (EMF) in the wire.

Front

What role does a rotor play in a motor?

Back

The rotor converts electrical energy into mechanical energy.

Front

What is the function of a generator?

Back

To convert mechanical energy into electrical energy.

Front

What is the relationship between electricity and magnetism?

Back

Electricity can create a magnetic field, and a changing magnetic field can induce an electric current.
