An electromagnet can pull with 100N on ferromagnets 0.5cm away, when r is near zero the force increases significantly, what are the possible methods of keeping that same rate of force (100N) applied over large distances over 0.5cm?
Increasing the size of the electromagnet? Or applying more voltage?
