Front

What is a solenoid?

Back

A solenoid is a coil of wire that generates a magnetic field when an electric current passes through it.

Front

What does the Right Hand Rule help determine?

Back

The direction of the magnetic field around a current-carrying wire.

Front

What is the definition of electricity?

Back

Electricity is the flow of electric charge, typically through a conductor.

Front

What is a magnetic field?

Back

A magnetic field is a region around a magnetic material or a moving electric charge within which the force of magnetism acts.

Front

What is the difference between AC and DC current?

Back

AC (Alternating Current) changes direction periodically, while DC (Direct Current) flows in one direction.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

What is the function of a battery in an electric circuit?

Back

A battery provides the electrical energy needed to drive the current through the circuit.
