Topic 7 Magnetism and Electromagnetism

Question 1

All magnets produce a magnetic field this a —– ——-force. The lines always go from —— to ———. The closer together the lines the:

Answer 1

non contact
north south

stronger the magnetic field

Question 2

The force between a magnet and a magnetic material is always attractive. no matter the ——

Answer 2

pole

Question 3

Answer 3

inside a compass is a tiny bar magnet (the needle) . the north pole of this magnet is attracted to the south pole of any of any other magnet it is near. So the compass needles points in the direction of the magnetic field it is in.
