Day 5 Class 6 Magnetic Field Strength

Multiple Choice

Which of today’s learning goals involves testing different magnets to see which is stronger?

• Understand magnetic field strength

• Identify strong and weak areas

• Compare different magnets

• Remember magnetic poles

Multiple Choice

Where is the magnetic field of a magnet the strongest?

• At the poles

• At the center

• Everywhere equally

• Nowhere

Open Ended

A magnet can attract objects equally strongly no matter how far away they are.

Open Ended

What happens to magnetic strength as you move a paper clip farther from a magnet?

Multiple Choice

Where are magnetic field lines densest, showing strongest force?

• At the poles

• At the center

• Far away

• Randomly everywhere

Open Ended

When field lines are spread apart, the field is weaker.

Multiple Choice

If Magnet A pulls a paper clip from 12 cm and Magnet B pulls it from 8 cm, which is stronger?

• Magnet A

• Magnet B

• Both equal

• Neither

Multiple Choice

Which is true about magnetic field strength?

• It is uniform everywhere

• It is strongest near poles

• It increases with distance

• It is strongest at the center

Multiple Choice

As we move away from a magnet in any direction, what happens to field strength?

• Increases

• Decreases

• Stays same

• Doubles

Open Ended

Why does the strength of a magnetic field decrease with distance?

Open Ended

Why do you think strong magnets are used in motors and generators instead of weak ones?
