No - magnet motor - telugu

Instead of a permanent magnet this motor has an electromagnet which is made by winding insulated copper wire on a sewing machine bobbin. its spinning coil is made out a meter long insulated copper wire. on one end the entire insulation is scraped. on the other only 3-sides are scraped. the remaining insulation forms an on - off switch. a 1.5-volt battery is sufficient to run this splendid motor.
