36.1 – magnetic poles

36.1 – magnetic poles

36.1 – magnetic poles. Always have two poles 1 pole seeks north, other seeks south Like poles  repulsive Unlike  attractive All magnets have two poles. 36.2 – magnetic fields. Direction of force when magnet is placed in someone else’s location Usually a compass
