Answer» Explanation: 63.. because at the point of intersection there will be 2 north poles which is not possible 64... spilt rings change the direction of the FLOW of current in a electric motor 65... 1.. move the magnet TOWARDS or away from coil 2.. increase the current in other coil which should be placed beside the coil 3.. increase the SIZE of magnet 4... increase the length of the coil 66....principle: it converts electrical energy to mechanical energy pls mark as brainlist hope it helps you |
