Magnetism in motion

Open Ended

Why do you think magnetism is important in our everyday lives, and can you give an example of where you might encounter it?

Multiple Choice

How does the alignment of magnetic domains affect the strength of a magnet?

• Aligned domains increase magnetic strength.

• Randomly oriented domains create a stronger magnet.

• Alignment has no effect on magnetism.

• Domains must be in pairs to be magnetic.

Multiple Choice

What happens when you bring the north pole of one magnet close to the south pole of another magnet?

• They attract each other.

• They repel each other.

• They lose their magnetism.

• Nothing happens.

Open Ended

Explain how magnetic fields allow magnets to exert force without direct contact. Use examples from daily life if possible.

Multiple Select

Which of the following statements about electromagnetism are correct?

• Electric current flowing through a wire creates a magnetic field.

• Electromagnets can be turned on and off.

• Electromagnetism is not used in modern technology.

• Magnetic fields are created only by permanent magnets.

MRI machines use super-strong

fields to align hydrogen atoms in the body.

Multiple Choice

What is the main advantage of maglev trains compared to traditional trains?

• They use less electricity.

• They float above the tracks, reducing friction.

• They are slower than regular trains.

• They do not use magnets.

Multiple Choice

Inside a phone speaker, what two components work together to create sound?

• Electromagnet and permanent magnet

• Battery and wire

• Speaker cone and plastic case

• Electric current and resistor

Multiple Choice

Which of the following is NOT an example of how magnetism is used in everyday life?

• Navigation using compasses

• Data storage in credit cards

• Cooking food in a microwave

• Security systems with magnetic locks

Multiple Choice

Which of the following best describes how magnetic domains contribute to magnetism?

• When domains are scattered and facing different directions, magnetism is strong.

• When domains are perfectly aligned, magnetism is strong.

• Magnetism does not depend on the alignment of domains.

• Domains must be destroyed for magnetism to occur.
