... If you hold two magnets together, they do not act like most objects. If you try to push the two north poles (N) together, they repel each other. If you try to push the two south poles (S) together, they also repel. Now, turn one magnet around and the north (N) and the south (S) poles attract. The ma ...

... 1. On each track on the back, mark points where the magnetic curve intersects the line of zero field strength. Start at the ridge and work outwards on both sides. These points are the points of reversals, when the magnetic pole switches from normal to reversed polarity or vice versa. Use a pencil! 2 ...

Force between magnets
Magnets exert forces and torques on each other due to the complex rules of electromagnetism. The forces of attraction field of magnets are due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the material. Both of these are modeled quite well as tiny loops of current called magnetic dipoles that produce their own magnetic field and are affected by external magnetic fields. The most elementary force between magnets, therefore, is the magnetic dipole–dipole interaction. If all of the magnetic dipoles that make up two magnets are known then the net force on both magnets can be determined by summing up all these interactions between the dipoles of the first magnet and that of the second.It is always more convenient to model the force between two magnets as being due to forces between magnetic poles having magnetic charges 'smeared' over them. Such a model fails to account for many important properties of magnetism such as the relationship between angular momentum and magnetic dipoles. Further, magnetic charge does not exist. This model works quite well, though, in predicting the forces between simple magnets where good models of how the 'magnetic charge' is distributed is available.
