What are the diff3rences between an electric field and a magnetic
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.
