What is a permanent magnet?
A material that can be magnetized for a very long time.
What does the magnetosphere do?

Electrons colliding with Nitrogen causes what colour?
Blue
Explain how temporary magnets work?
Electrons from objects that have a magetic field transfer over to an object due to friction. These electrons move in one direction increasing the magnetism of the object.
