How to repair magnets

Over time magnets lose their properties, although this may occur over decades. In addition, magnets can be accidentally deprive properties when heated to a certain temperature. In any case, if their actions depends on the work of, for example, motor boats, sometimes it's easier to recover the magnets, than to buy a new one.

You will need

• – a magnet or a blank of electrical steel or a ferrite;
• – wire of PEV;
• thin copper conductor 0,05;
• – fuse Meringue;
• – AC or DC;
• – high voltage battery or battery;
• – capacitor;
• – powerful magnet.

Instruction

1. If you want to get properties of the magnet in the internal combustion engine, first remove the base of the magneto, the ignition coil and remove the iron tip. Install the magnet on the corner of the table, remote from large metal objects and radiators.
2. Wrap over the core 500-1000 turns of wire of PEV in diameter of 0.1-0.8 mm in a time frame. If you need to magnetize a horseshoe-shaped core, the winding to produce in the bend magnet, or divide it into two halves and move to different poles.
3. The ends of the windings connect with thin copper conductor, of a thickness not exceeding 0,05 mm. connect the magnet through the conductor in a network of DC or AC or high-voltage battery (battery). Instead of a thin conductor to ensure the safety, you can use the Bose fuse in a glass tube.
4. Be careful at the time of passage of current, since the magnet when it is magnetized, and the conductor is burned (melted), and its spray can get into eyes and skin. Try to stay away from construction, keep the children and animals.
5. Gather the following installation: the coil in 50-200 turns and inside her former magnet or any blank of electrical steel and the coil dimensions must be 30-40% more than the size of the magnet. Orient the magnet in the desired direction relative to the field in the coil: either perpendicular or along the surface. Then charge the capacitor with a capacity of at least 5,000 microfarads and discharge it into the coil. To activate the system, use the push button switch: "charge" capacitor "discharge" through the coil.
6. A little to restore the properties of the magnet (temporarily), place it near a powerful current magnets with the correct polarity. After a month, assess the condition of the magnet – it will work much better.
