Exploring Magnetism and Forces

Front

What is the difference between mass and weight?

Back

Mass is a measure of matter, while weight is the force of gravity acting on that matter.

Front

What device uses a magnet to function?

Back

A compass uses a magnet to indicate direction.

Front

What happens when the north pole of one magnet is brought close to the south pole of another magnet?

Back

They attract each other.

Front

How is a magnetic field best described?

Back

An invisible field that exerts magnetic force on substances sensitive to magnetism.

Front

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

Back

Each half will have both a north and a south pole.

Front

What is magnetism?

Back

Magnetism is a force that can attract or repel certain materials, primarily metals like iron.

Front

What materials are typically attracted to magnets?

Back

Materials like iron, nickel, and cobalt are typically attracted to magnets.

Front

What is a magnetic pole?

Back

A magnetic pole is one of the two ends of a magnet where the magnetic force is strongest; one is a north pole and the other is a south pole.

Front

What is the role of gravity in determining weight?

Back

Gravity pulls on mass to create weight; weight is the force exerted by gravity on an object.

Front

Can magnets repel each other?

Back

Yes, magnets can repel each other when like poles (north-north or south-south) are brought close together.
