What is a magnetic field?

• A type of force that ONLY repels magnets and electric charges

• A force field that surrounds magnets which can repel and attract objects.

What are the two types of magnetic poles?

• East pole and West pole

• Positive pole and Negative pole

• Up pole and Down pole

• North pole and South pole

What happens when two like magnetic poles are brought close together?

• They attract each other (come closer together)

• They merge into a single pole

• They create a neutral field

• They repel each other (push each other away)

What happens when two unlike magnetic poles are brought close together?

• They repel each other. (push away)

• They attract each other. (they come together)

• They have no effect on each other.

• They create a neutral field.

What is the relationship between the strength of a magnetic field and the distance from the magnet?

• The strength of a magnetic field increases as the distance from the magnet increases.

• The strength of a magnetic field remains constant regardless of the distance from the magnet.

• The strength of a magnetic field decreases as the distance from the magnet increases.

• The strength of a magnetic field is not affected by the distance from the magnet.
