How is current related to magnetic field
Web28 mrt. 2015 · A winding (conductor) carrying direct current (DC) produces a magnetic field akin to a permanent magnet. The current carried by this conductor is unidirectional and steady i.e. it does not change direction or vary in magnitude with respect to time. Hence, the effect is that of a permanent magnet which simply attracts objects near the coil. Web5 nov. 2024 · The apparatus used by Faraday to demonstrate that magnetic fields can …

The 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 the component of the force that is independent of motion.
