Which poles repel? (mark 2 correct answers)

• North and South

• South and North

• North and North

• South and South

• None of these, only magnetic monopoles will repel.

Which is not a property of a magnet? 

• all magnets have two poles
• all magnets have a force of attraction or repulsion
• all magnets are surrounded by a magnetic field
• all magnets can be turned off

How is Earth's magnetic field similar to that of a magnet?

• It's shaped like a horseshoe.
• It has north and south poles.
• It is made plastic.
• It is hundreds of miles long.

The magnetic domains in this substance are not highly aligned. This substance is therefore

• magnetized

• unmagnetized

• positively charged

• negatively charged

What will happen when these magnets are brought close together?

• They will attract each other.
• They will repel each other.
• Both magnets will turn to the left
• Both magnets will turn to the right
