I believe AC electromagnets are possible, but they are trickier to make. Finally, push the needle into a piece of cork… To make a compass, you must first magnetize a needle by rubbing its endpoint with a magnet about fifty to a hundred times. At the sharp end he had a south pole, and dull - north. Poker, we magnetized very simple. Each iron bar or a piece of iron, which would be placed and the plane of the magnetic meridian, magnetized. It has long been observed that iron pipes or rods, stood stock more or less long time, acquire magnetic properties. At the lower end they formed the North Pole, and on top - the south.This magnetization is the stronger, the more precisely one end of an iron stick will be sent to the South Magnetic Pole, which is located near the north geographic pole. In our northern hemisphere this end will always be lower.  If an iron rod is made ​​of soft iron on (chemically pure), it is magnetized immediately as soon as it is given according to the direction. But ordinary corrupt iron is not pure iron, carbon zhelezom- it. It is magnetized very slowly.  However, the c reproach magnetization can be strong and sharp shocking magnetized poles. Also, avoid the strongest neodymium magnets; though they have important uses in science and industry, their powerful magnetic fields can make them dangerous to handle, especially in the presence of iron or steel objects. This is a magnet that has the poles labeled on it. magnet strength may be done based on the performance of the entire device, rather than that of the magnet alone, thus removing an entire range of variables. Watch Queue Queue. Float the magnetized needle very carefully on the surface of the water. How To Magnetize A Person Place the subject on a chair before you, a little lower than your own, if convenient, and in a perfectly easy position with his feet near together.

Pull the magnet away from the compass. If I turn a demag off while my workpiece is still on it, will it create a magnet? When we repeat the process of magnet then in that case the torque due to magnetic field on all the domains will align them in one direction. It’s very simple: all you need to do is hold the south pole of the old magnet to the north pole of the neodymium magnet. This is a great way to re-magnetize the needle of a compass. 1).

Begin to move the magnet over the side of the screwdriver, without detaching it. Move a magnet from the top of a needle to its point fifty times. You can use this same method to re-magnetize old ceramic, ferrite or Alnico magnets. 1. You are absolutely right. Not being familiar with the geometry of your pill grinder, it's hard to say. Place a heavy piece of metal on a scale and zero the scale. Then, stroke the north end of the magnet against the metal about a dozen times in the same direction to create a magnetic charge. "I remembered learning, as a child how to make a magnet by rubbing a piece of metal with a magnet. Test the needles magnetization by trying to pick up the third needle.
