Define magnetic field .

A magnetic field is a field of force created by a moving electric charge or by a permanent magnet .

Does a stationary electric charge produce a magnetic field?

No. A magnetic field is only produced by a moving charge (or by a permanent magnet ).

From the north pole to the south pole.

Field lines closer together indicate a stronger field; field lines further apart indicate a weaker field.

False. Magnetic field lines never cross.

Two like magnetic poles repel each other, while two opposite poles attract each other.
