Critical Juncture Magnetic Fields

Front

What is a variable?

Back

A variable is something that can be changed and measured.

Front

What happens when two magnets are held close and then let go?

Back

The magnets will move away from each other because the magnetic force will push the magnets apart.

Front

What will happen to two magnetic toy trains placed close to each other?

Back

The trains will move away from each other because the magnetic force will push the trains apart.

Front

What is a magnetic field?

Back

The space around a magnet in which magnetic forces can act on objects.

Front

How can you increase the potential energy in a system with magnetic carts?

Back

Moving the cart on Track 1 one space to the left will increase the potential energy the most.

Front

What is the effect of like magnetic poles on each other?

Back

Like magnetic poles repel each other.

Front

What is the effect of opposite magnetic poles on each other?

Back

Opposite magnetic poles attract each other.

Front

What is a magnetic field line?

Back

A magnetic field line is a visual representation of the magnetic field, showing the direction and strength of the magnetic force.

Front

What is the role of a magnet's poles?

Back

The poles of a magnet are the regions where the magnetic force is strongest.

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.
