Magnets and electromagnets

Front

What is a magnet?

Back

A magnet is an object that produces a magnetic field, which can attract or repel certain materials, such as iron.

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 kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state.

Front

How do magnets interact with each other?

Back

Magnets can either attract or repel each other depending on their poles: like poles repel, while opposite poles attract.

Front

What happens when a magnetic field is produced?

Back

When a magnetic field is produced, it can exert a force on other magnets or magnetic materials within the field.

Front

What is the role of a switch in an electric circuit?

Back

A switch controls the flow of electric current in a circuit, allowing it to be turned on or off.

Front

What is the relationship between electric current and magnetism?

Back

Electric current flowing through a wire generates a magnetic field around the wire.

Front

What are magnetic field lines?

Back

Magnetic field lines are imaginary lines that represent the direction and strength of a magnetic field.

Front

What is the effect of distance on magnetic force?

Back

The strength of the magnetic force decreases as the distance between two magnets increases.
