1.Electric forces can be produced by either stationary or moving electric charges, whereas magnetic forces can be produces only by moving charges.
Magnetic force on a moving charge is always normal to the direction of the movement and the magnetic field whereas the force by an electric field on a moving charge is always parallel to the electric field and does not depend on the direction of movement.
2.Without using a compass, there is a simple way of finding which is the north pole or south pole of an electromagnet. Turn the electromagnet so that the end faces your eye. If the electricity travels clockwise around the electromagnet then the end you are looking at is the south pole.
