magnetism

As the distance between two magnets increases (they get farther apart), the force between them:

• Increases
• Decreases
• Stays the Same

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

What is a ferromagnetic material?

• A material which is exhibits very strong magnetic effects.

• A material which is exhibits very weak magnetic effects.

• A material which is exhibits no magnetic effects.

A magnetic field exerts a force on a charged particle:

• always

• never

• if the particle is moving across (or perpendicular) the field lines

• if the particle is moving along (or parallel) the field lines

• if the particle is at rest

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

• Attract
• Repel
• Do nothing
• Shatter

F = qvB If the speed and charge double, what happens to the magnetic force?

• halves

• remains the same

• doubles

• quadruples

What is the direction of the force?
