Process to create a magnet

Magnets are quite popular now, but not everyone knows how to create them. Different hard magnetic materials require completely different processes. You can refer to the steps to create a magnet through the article below. – AlNiCo is not only a special alloy but also highly resistant to magnetism. In order to make this material you can mix aluminum, nickel, cobalt together in appropriate proportions. Then proceed to melt this compound and finally the heat treatment step to compound the [...]

Scientists have found a way to make ultra-thin magnets at just one atom

It is calculated to work only in two dimensions because the charge can only move at the atomic level, which is similar to how chess moves on a chessboard. You have probably heard about graphene metamaterials with extremely thin dimensions, just a layer of carbon and extracted from lead ore. Now scientists at the University of Washington and the Massachusetts Institute of Technology have applied graphene-based lead separation technology to develop the world’s thinnest magnet. It was so thin that it [...]

See how objects are crushed by two magnets

Youtube channel Firstformagnets is famous for its excellent videos of “Permanent Magnets”, recently they made a very interesting clip, which is using two magnets to grind things. Thanks to the Slow-mo effect, the moment the object is subjected to two strong magnets becomes extremely impressive. The apples are soaked by the pressure of the two magnets.
