Amplify - Magnetic Fields - Flashcard

Front

What is the effect when two magnets are brought close together?

Back

They can either attract or repel each other depending on their poles.

Front

What is a compass?

Back

A device that has a magnetized needle that can spin freely, used for navigation.

Front

What happens to potential energy when two magnets move due to magnetic force?

Back

Some of the potential energy is converted to kinetic energy.

Front

What do magnetic field lines represent?

Back

They represent the magnetic force around magnets and the earth.

Front

What is the direction of magnetic field lines around a magnet?

Back

They flow from the north pole to the south pole.

Front

What is the difference between attracting and repelling forces?

Back

Attracting forces pull objects together, while repelling forces push them apart.

Front

What is a magnetic field?

Back

A region around a magnet where magnetic forces can be detected.

Front

How can you visualize magnetic field lines?

Back

They can be visualized using iron filings sprinkled around a magnet.

Front

What happens to the magnetic field when a magnet is cut in half?

Back

Each half becomes a new magnet with its own north and south poles.

Front

What is the role of magnetic fields in electric motors?

Back

They interact with electric currents to produce motion.
