Electricity and magnetism

Front

What is a conductor?

Back

A material that allows electrons to flow easily, enabling the conduction of electricity.

Front

What is an insulator?

Back

A material that does not allow electrons to flow easily, preventing the conduction of electricity.

Front

What happens when like poles of magnets are placed next to each other?

Back

They repel each other.

Front

What happens when opposite poles of magnets are placed next to each other?

Back

They attract each other.

Front

What is the role of a battery in an electromagnet?

Back

The battery provides the electricity needed to create a magnetic field.

Front

What is magnetism?

Back

A force that can attract or repel certain materials, primarily metals like iron, and is produced by the motion of electric charges.

Front

What is an electromagnet?

Back

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

Front

What is grounding in electrical systems?

Back

The process of transferring excess electrical charge to the earth to prevent electrical shock and equipment damage.

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 only.

Front

What is static electricity?

Back

An imbalance of electric charges within or on the surface of a material, often resulting in a shock when discharged.
