Making a permanent magnet; home ... You are in: Home > Experiments > Making a permanent magnet ... Making a home-made permanent magnet is impossible. I have tried to do, but so far not one is success: they always lose their magnetism easily if they are knocked. One must superheat the unmagnetised magnet until it's hot and must...

A good permanent magnet should produce a high magnetic field with a low mass, and should be stable against the influences which would demagnetize it. The desirable properties of such magnets are typically stated in terms of the remanence and coercivity of the magnet materials.

In a permanent magnet machine, ... Notice the magnet in the center of the block. The rod (1/8" steel) that serves to move the block up and down, is attached ONLY by the force of this magnet. This allows for some flexibility between the block and the rod, to aid in making good contacts between the brass and the carbon.
