2 Non-contact force Contact force
Hang a magnet from a clamp stand using a piece of string Bring another magnet close to the end of the hanging magnet – do not let them touch. Try both end of both magnets – there are 4 combinations. Non-contact force Use a Newton meter to measure how much force is needed to drag the shoe across the desk. Add 100g masses to the shoe and observe its effect on the force needed. Contact force
