Magnetism is not well understood. Even the makers of magnets don’t understand how it actually works! There is starting to be an understanding of what magnetism really is. Why is it important? Well everything is a magnet. When you have a compass it points north due to earth’s magnetism. When you coil a wire multiple times and put electricity through it, it creates a magnet. A device called a ferrocell has been created to visualize magnetism in 3D. There are instructions on how to make one at home online. The standard visualization method using iron filings does not give magnetism justice. Checkout this site to see more visuals and to better understand magnetism for yourself. Additionally, magnets are not as simple as having a north pole and south pole. Different regions of the magnet actually cause either acceleration or deceleration. Our earth shows such phenomenon as the northern lights. You can read a free book “Uncovering the Missing Secrets of Magnetism” by Ken Wheeler here. Give your thoughts on the implications of this, there are many natural and human inventions (Rodin coil) made which mimic and take advantage of this.
