notably thin-walled ring magnets that proved ideal for use in small motors. The development of neodymium–iron–boron permanent magnets has allowed the miniaturization of motors and hard disk ...

Luckily, there’s more than one way to make a magnet, and it may soon be possible to build permanent magnets as strong as neodymium magnets, but without any rare earth metals. In fact ...

Magnets have always been fun, particularly since the super-powerful neodymium type became readily available. You can stack them up, pull them apart, or, if you really want, use them for something ...

MP Materials has launched domestic production of a rare-earth magnet it intends to mass produce for General Motors and other U.S. customers, in what it frames as a move towards import substitution ...

This is why iron and neodymium magnets are used in everything ... Convert electrical signals into sound using magnets. MRI Machines: Use powerful magnetic fields to scan inside the human body.

SAFETY: Neodymium magnets are surprisingly powerful when they ... plastic pipe of similar dimensions to the copper pipe to use as a comparison If you have a plastic pipe, hold it vertically ...

While magnetic knife blocks can be expensive, you can make your own using the powerful neodymium magnets in a hard drive ... you can still get some use out of them by turning them into a desk ...

THERE seems to exist a discrepancy between the measured value of the alpha-decay half-life of natural samarium (samarium-147) and the theoretical half-life calculated from its measured alpha energy 1.

Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and sizes. Bar magnets and horseshoe magnets are two of the most common shapes ...
