The aim of this module is to teach you the basic laws of electric and magnetic fields, their application to elementary problems involving steady and time changing fields and currents, and give you an ...
It looked still to you before because you were moving with it. We have this same problem with electric and magnetic fields. Depending on your reference frame, what appears to be a magnetic force ...

Scientists create magnetic device to capture electricity from Earth’s rotational dynamicsA wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new ...
“The electric and magnetic fields at a material’s atomic level determine its bulk properties and behavior, and are an essential area of research,” says Toshiaki Tanigaki, a senior researcher ...
Plotting compasses can also be used to see the magnetic field around a solenoid. To make a loudspeaker cone vibrate correctly, the electric current must vary in the same way as the desired sound.
