If you connect a wire loop to a battery, the battery sets up an electric field in the wire. The electric field does work on the charge. Inside the battery, the battery provides the energy to push the (negative) charges at the positive terminal (low potential energy) to the ...
infinitely great motional speed; the same physical phenomenon can be explained conversely in different inertia systems; there is no uniform scientific explanation for deflection of high-speed charged particle in magnetic field; coexistence of static magnetic field with static electric field cannot be ...
