Magnetism

If you cut a magnet in half, what happens to the poles?

• One half gets the North Pole, the other half gets the South Pole
• Both halves get only a North Pole
• Both halves get only a South Pole
• Both halves get a North pole and a South Pole

If the North Pole of a permanent magnet is placed next to a compass as seen in the picture, which direction will the needle move?

• Clockwise
• Counter-clockwise
• It will not move
• Need more information

What kind of magnet can be turned on and off?

• refridgerator magnet
• electromagnet
• magnetite
• iron

The strongest part of a magnet is...

• the bars.
• the force field.
• the poles. 
• the middle.

If a glass plate is placed over a magnet and iron filings are sprinkled over the glass, a pattern will be visible. What does this pattern indicate?

• The magnetic field

• The electrostatic field

• The piezoelectric effect

• The chemical reaction of the magnet and the filings

What do the lines around this magnet represent?

• North Pole
• South Pole
• Magnetic Declination
• Magnetic Field

The diagram below shows a bar magnet. Which direction best represents the direction of the needle of a compass placed at point A?

• left
• right
• up
• down

If you place the North pole of a magnet next to the South pole of another magnet, they will:

• Attract
• Repel
• Do nothing
• Shatter

A paper clip is an example of a:

• magnetic material
• permanent magnet
• bar magnet
• insulator

What happens when two north poles of a magnet are placed together?

• they repel
• they attract
• they cancel each other out
• the strength of the magnet is doubled
