Critical Juncture Magnetic Fields

Front

What is a magnetic field?

Back

A magnetic field is a region around a magnet where magnetic forces can be detected. It is represented by field lines that show the direction and strength of the magnetic force.

Front

What are the two types of magnetic poles?

Back

The two types of magnetic poles are North and South. Like poles repel each other, while opposite poles attract.

Front

What happens when you bring two north poles of magnets together?

Back

The two north poles will repel each other.

Front

What happens when you bring a north pole and a south pole of magnets together?

Back

The north pole and south pole will attract each other.

Front

What is potential energy in the context of magnetic fields?

Back

Potential energy in magnetic fields refers to the energy stored due to the position of magnets relative to each other. It decreases when magnets are brought closer together.

Front

How can you decrease potential energy between two magnets?

Back

You can decrease potential energy by moving the magnets closer together.

Front

What does 'attract' mean in terms of magnets?

Back

To attract means to pull together, as when opposite poles of magnets come close to each other.

Front

What does 'repel' mean in terms of magnets?

Back

To repel means to push away, as when like poles of magnets are brought close to each other.

Front

What is the significance of magnetic field lines?

Back

Magnetic field lines visually represent the strength and direction of a magnetic field. The closer the lines, the stronger the magnetic field.

Front

What is the role of magnetic fields in electric motors?

Back

Magnetic fields interact with electric currents in motors to produce motion, converting electrical energy into mechanical energy.
