Webb5 nov. 2024 · It should be emphasized that the electric force F acts parallel to the electric field E. The curl of the electric force is zero, i.e.: (21.4.3) ∇ × E = 0 A consequence of this is that the electric field may do work and a charge in a pure electric field will follow the tangent of an electric field line. WebbA moving electric charge can generate a magnetic field, while with the help of a magnetic field, electric current can be induced into a conductor. Hans Christian Oersted was the first person to observe that a needle of the compass did not point towards the north pole when it was brought near a wire through which an electric current was flowing.

Webb17 maj 2024 · An electric current is usually thought of as a flow of electrons. When two ends of a battery are connected to each other by means of a metal wire, electrons flow out of one end (electrode or pole) of the battery, through the wire, and into the opposite end of the battery. An electric current can also be thought of as a flow of positive "holes."
