Critical Juncture Magnetic Fields

Front

What is a magnetic field?

Back

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

Front

What is an electromagnet?

Back

A type of magnet in which the magnetic field is produced by an electric current.

Front

What happens when two magnets are brought close together?

Back

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

Front

What is potential energy in the context of magnets?

Back

The stored energy of an object due to its position in a magnetic field.

Front

How does distance from a magnet affect potential energy?

Back

The farther an object is from a magnet, the lower its potential energy.

Front

What is the effect of moving a magnetic object away from a magnet?

Back

It increases the potential energy of the object.

Front

What is the role of magnetic poles?

Back

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

Front

What is the difference between a static magnet and an electromagnet?

Back

A static magnet has a constant magnetic field, while an electromagnet's field can be turned on and off with electric current.

Front

What is magnetic force?

Back

The attraction or repulsion that occurs between magnetic objects.

Front

What happens to the potential energy of a roller coaster car as it moves away from a magnet?

Back

The potential energy of the car increases as it moves away from the magnet.
