electromagnets and circuits ELL

Front

What happens when the positive pole of one magnet is placed next to the negative pole of another magnet?

Back

The magnets will attract.

Front

How do magnets interact with each other based on their poles?

Back

Magnets can attract or repel each other.

Front

What is the term for a pathway taken by an electric current?

Back

A circuit.

Front

What occurs when the positive poles of two magnets are facing each other?

Back

The magnets will repel.

Front

Why are magnets important in electrical circuits, such as generators?

Back

They are used to convert mechanical energy into electrical energy.

Front

What is the definition of 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 role of a switch in an electrical circuit?

Back

A switch controls the flow of electric current by opening or closing the circuit.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected end-to-end, so the same current flows through all components. In a parallel circuit, components are connected across common points, allowing multiple paths for current.

Front

What is magnetic field strength and how is it measured?

Back

Magnetic field strength is a measure of the intensity of a magnetic field, typically measured in teslas (T).

Front

What is the principle of electromagnetic induction?

Back

Electromagnetic induction is the process by which a changing magnetic field can induce an electric current in a conductor.
