|
What is the reason that iron filings stick more to the ends of a magnet rather than the middle? |
|
|
Card: 18 / 42
|
The magnetic force is strongest at the poles of a magnet, which is why iron filings gather more densely at the ends. |
|
|
Card: 19 / 42
|
True or False: It is possible to find a magnet with only one pole. |
|
|
Card: 20 / 42

Explain why breaking a magnet into smaller pieces does not result in a single North or South pole. |
|
|
Card: 22 / 42
|
When a magnet is broken, each piece retains both a North and a South pole due to the intrinsic nature of magnetic dipoles. |
