moving charges and magnetism magnetism

2) When the charges move parallel or anti-parallel to the magnetic field, q = 0 o or 180 o , the is zero in such cases. ..

Introduction - The branch of physics which deals with magnetism due to the electric current is called electromagnetism. For a long time it was hard to believe if there existed a relation between electricity and magnetism. Hans Christian Oersted observation made a discovery demon..
