The magnetic poles.

After having found out about the poles of the earth in geography Year 3 have been investigating how magnetic poles attract and repel each other.  We made predictions and tested different materials to test there magnetism.

Questions we had were:

Q. Why did some materials attract the magnet and some repel them?

Q. Are all metals magnetic?

Q. Could the magnet still have an impact on the object when another material was between them?
