📚 Topic Summary
Magnetism is a force that attracts or repels certain materials, like iron and nickel. This force is created by the movement of electric charges in the atoms of these materials. Magnets have two ends, called poles: a north pole and a south pole. Opposite poles attract each other (north pulls south), while like poles repel each other (north pushes north, south pushes south). This invisible force extends around the magnet, creating a magnetic field. Earth itself is a giant magnet, which is why compasses work!
