Electric field                        Magnetic field

The region of space around an           The region of space around a
electric charge where its effect         magnet where the effect of

           appears in it.                     magnetism appears.

Electric field lines                   Magnetic field lines

            Imaginary lines don’t intersect

Start from +ve charge.            Start from north pole of the magnet.

End at -ve charge.                     End at south pole of the magnet.

They end at the surface of charged They are denser near the poles and

objects and don’t penetrate them far separated as they move away

                                       from them.

“Invisible forces” We can only observe their effects.

“Non-contact (Field) forces” Not necessary for objects to be in contact to get
                                          affected.

It attracts any object has mass It attracts certain “magnetic” materials

It is always downward pulling force. It is considered as pulling force
                                                  “attract” or pushing force “repel”.
