Magnets and electricity

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 are the two poles of a magnet?

Back

The two poles of a magnet are the north pole and the south pole. Opposite poles attract each other, while like poles repel.

Front

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and electrical devices.

Front

What is the role of a power source in a circuit?

Back

The power source, such as a battery, provides the energy needed to push electric charges through the circuit.

Front

What happens to the magnetic field strength as you move away from a magnet?

Back

The strength of the magnetic field decreases as you move away from the magnet.

Front

What is demagnetization?

Back

Demagnetization is the process of removing the magnetic properties from a magnet, which can be done by heating, hammering, or dropping it.

Front

How do magnets interact with each other?

Back

Magnets interact by attracting or repelling each other based on their poles: north attracts south, and north repels north.

Front

What is Earth's magnetic field?

Back

Earth's magnetic field is the magnetic field that surrounds the planet, generated by the movement of molten iron in its outer core.

Front

Where is Earth's magnetic South Pole located?

Back

Earth's magnetic South Pole is located approximately 10 degrees from Earth's geographic North Pole.

Front

What materials are attracted to magnets?

Back

Materials such as iron, nickel, and cobalt are attracted to magnets due to their magnetic properties.
