The magnets sold by the most of the major prospecting shops to separate out black sands will not do. Those old style magnets will pick up magnetite, but not hematite. The new powerful rare earth super magnets are necessary because they will pick up the hematite, which is only very slightly magnetic.

Neodymium magnets pull towards each other with a strong force. If you try pulling two magnets directly apart, you need quite a bit of force to pull them apart. To separate one magnet from another, you'll need to pull with a force equal to the listed Pull Force Case 1 number. This can be difficult if the magnet is strong, or if there isn't much ...

Separating magnets relies on a few simple principles: Create an air gap. Slide don't pull. Often our neodymium magnets come with a plastic or heavy cardboard spacer between them. It's helpful to keep these for future storage. As a rule of thumb, the stronger the magnet, the thicker the spacer should be. Spacers simply provide a non ...

Gold, in its pure form, is not magnetic. It is known as a diamagnetic material because it has a weak repulsive force toward magnets. But when gold is alloyed with metals like zinc, copper, nickel, iron, cadmium, aluminum, silver, platinum, and palladium, it may display magnetic properties. Aside from gold, other non-magnetic metals include ...
