Question:
What are the diff3rences between an electric field and a magnetic field?



Replies:
An electric field exerts a force on stationary electric charges, while a magnetic field exerts no force on non-moving charges. A magnetic field does exert a force on magnetic objects (such as a dipole magnet). One of the interesting things about electric and magnetic fields, however, is that when you are moving they can change from one form to the other. That is, a moving charge creates magnetic fields, even though a stationary charge creates only electric fields. This is why the two are tied together in the theory of electromagnetism.
