Electromagnetism in one slide Electric charges q establish electric fields E everywhere in space. An electric charge experiences an electric force F E =q E , where E is the electric field at the charge’s position, and q is the magnitude of the charge. Moving electric charges result in electric currents; electric currents establish magnetic fields B everywhere in space. A moving charge q experiences a magnetic force F B =q v × B , with v the velocity of the charge and B the magnetic fields at the location of the charge. Magnetic fields can also be established by time-varying electric fields. Likewise, electric fields result from time- varying magnetic fields. These coupled effects produce electromagnetic waves.
