How do you make a screwdriver with a magnetic tape?
Rub on the magnet and move back and forth, but note that if the "come" is attached to the magnet, then the "back" should be pulled up and not attached to the magnet, which is more effective than aimless rubbing
If the screwdriver is magnetic, if it is fast, rub it on the magnet, or stick the magnet on the screwdriver so that it can absorb the screws
No words can be a magnet insulated fine wire wound in the screwdriver bar on the two ends of the wire, received less than 20 volts transformer on a few minutes with a magnet
