Unit 1: Magnetism and Electromagnetism

Front

What type of energy does a generator transform into electrical energy?

Back

Kinetic energy.

Front

What is the term for the ability of some materials to attract certain metals?

Back

Magnetism.

Front

Which direction does a compass point in relation to Earth's magnetic field?

Back

Toward the south pole of Earth's magnetic field, which is near the Earth's geographical north.

Front

What is the visual representation of magnetic forces around a magnet called?

Back

Magnetic field.

Front

What type of magnet can be turned on and off?

Back

An electromagnet.

Front

What is the relationship between electricity and magnetism in electromagnetism?

Back

Electricity can create magnetic fields, and changing magnetic fields can induce electric currents.

Front

What is the principle behind how a generator works?

Back

A generator converts mechanical energy (kinetic energy) into electrical energy through electromagnetic induction.

Front

What materials are typically used to make permanent magnets?

Back

Materials like iron, nickel, and cobalt.

Front

What is the role of a magnetic field in the operation of a compass?

Back

The magnetic field of the Earth influences the orientation of the compass needle, allowing it to point toward magnetic north.

Front

How does the strength of a magnetic field change with distance from the magnet?

Back

The strength of a magnetic field decreases as the distance from the magnet increases.
