magnetic fieldsThe force on an electric charge depends on its location, speed, and direction; two vector fields are used to describe this force. The first is the electric field, which describes the force acting on a stationary charge and gives .

magnetic fieldsPermanent magnets are objects that produce their own persistent magnetic fields. They are made of ferromagnetic materials, such as iron and nickel, that have been magnetized, and they have both a north and a south pole.The magnetic field . See moreForce between magnetsSpecifying the force between two small magnets is quite complicated because it depends on the strength and orientation of both magnets and . See moreThe formulas derived for the magnetic field above are correct when dealing with the entire current. A magnetic material placed inside a magnetic . See moreLike all vector fields, a magnetic field has two important mathematical properties that relates it to its sources. (For B the sources are currents and .
