Neodymium Iron Boron Magnets are usually called neodymium or rare earth magnets. They are very powerful, with a magnetic force 10 times greater than ferrite magnets and 20,000 times greater than the earth's magnetic field. These magnets are both fragile and powerful, and are easily broken. If proper care is taken when handling them, they can be used for many beneficial and creative purposes.
Put a 1/2 inch diameter Cylinder Neodymium Magnet in your pocket, it can be used as a tool holder. Any tools with metal handles or metal shafts will be fixed to your pants by magnets. If you don't want to risk tearing your pants, use glue to glue a button-sized magnet into the belt to make a magnetic tool belt. You can also make a magnetic tool rack for your studio by drilling a magnetic-sized hole on the back of a piece of wood, inserting a magnet into the hole, and then hanging the wood on the wall so that the magnet is hidden. Even if you can't see them, they still attract metal strongly.
If you have a collection of Neodymium Magnets, use your creativity to build a dreamy structure that seems to be able to fight gravity. For example, build a vertical wooden frame, embed a magnet in the top horizontal strip, and then glue the other magnet to the bottom rope. The magnet on the rope will be attracted by the magnet on the top, and it looks like it is hanging in the air. Use magnets of different sizes and shapes to approach your inner artist.
Cylinder Neodymium Magnet
Slide the neodymium magnet along a non-magnetic conductive surface (such as copper) and you will notice that the magnet resists movement, even if it is not attracted by the metal. This is because the moving magnetic field creates an electric field in the conductive material, and this electric field is the opposite of the magnetic field. This effect is called Lenz's law.
Put two grapes at the end of a straw, and fix the straw on a plastic bottle cap with a pin. Move the neodymium magnet next to the grape and it will move away from the magnet. Then, turn the magnet over. Although you think grapes will be attracted, they will be repelled. This is because the water in the grapes is dual magnetic and is repelled by the poles of the magnet.
Put an old CD on a rotating shaft so that it can rotate freely, and then glue a small neodymium magnet on it so that a magnetic pole is on the edge, facing outwards. Move the other neodymium magnet close enough so that the magnets repel each other and the CD will rotate. If you can find a way to synchronize the movement of free magnets and keep the CD spinning, you can completely change the energy industry.
