Concepts of electromagnetic force

By Andrew Joseph     December 31, 2020     Physics     No comments   

 

The word electromagnetic force consists of two qualitative distinct forces: electricity and magnetism. It is the force acting on either or both an electric charge or on a magnetic pole. It is called "electromagnetic" since the "electric" or "magnetic" nature of the force depends on how the object which is feeling that force is moving relative to the source-charges that are causing this force. For example, an electric charge moving in a magnetic field, i.e. near magnets, is experiencing an electric field, meaning it feels as if it were at rest near electric charges. It is customary to say that the "electric" or "magnetic" nature of the field o is a relative nature of the motion thus it is best to call this force "electromagnetic".
