Magnetic Forces

The video explains how magnetism is an invisible force caused by electron motion, leading to attraction and repulsion. Magnets have aligned electrons creating north and south poles, forming a magnetic field. Only certain materials, like iron, can form magnets. Earth itself is a giant magnet, enabling compass navigation. Magnets are crucial in technology, from motors to medical equipment.
