Under what circumstances can electrical charges produce a magnetic field?

Answer 1

Yes, a moving electric charge creates a magnetic field around its path of travel, and this is true for any charged particle. Further, it is the basis for the idea that the electromagnetic force is one force. Physics views electric fields and magnetic fields as being derived from just that one force we mentioned. When we see charges moving continuously, we will see a "standing" magnetic field around the current path. And the magnetic field can be made to do many useful things. This is the idea behind almost all electric power generation around the world as well as countless electronic applications.

Answer 2

The magnetic field must change - a static electric field won't produce electricity. Also, there must be some conductor through which the electricity can actually flow.

The point is that the field must change relative to the conductor, in most cases it is the conductor that is moved through a static magnetic field. This was first found by Faraday, more or less by chance I think, but it has now become the basis for all electrical generators where mechanical energy is converted to electrical energy

Answer 3

an electric charge,whenever is in motion(not in stationary condition) will give rise to a magnetic field. As the famous scientist Oersted found in his experiment.

Answer 4

Time Changes in Electrical charges, current I, creates a magnetic field, B=uI/r, where r is the distance form the current flow..

Answer 5

Only when it moves. An electric charge creates an electric field. A moving electric charge additionally creates a magnetic field.

Answer 6

Electromagnetism.
