positive polenoun PhysicsA north-seeking pole of a magnet.The main component of the Sun's magnetic field is similar to a bar magnet, with a positive pole and a negative pole....- Since growth of dendrite of lithium or zinc at the time of the charge can be prevented, short circuit between the negative pole and the positive pole can be prevented.
