How is current related to magnetic field
Web12 sep. 2024 · Since the currents are flowing in opposite directions, the net magnetic … WebWhere ϕ = force producing the field, ℛ = resistance to the magnetic flux (reluctance). The relationship between F in gilberts and ampere-turns is a factor of 1.257. This relationship is stated: F = 1.257I ×N F = 1.257 I × N. Where F is the force in gilberts, I is the electric current, and N is the number of turns.

Web20 jan. 2024 · The average velocity (drift velocity) of electrons is reduced. Therefore, the magnetic field is also decreased. In short, The temperature decreases the speed of particles (and so the current), decreasing the strength of the magnetic field. You're assuming a constant voltage source produces the current. raymond b winterThe 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. The magnetic field, in contrast, describes the component of the force that is proportional to both the … raymond byramWebThere are two basic ways which we can arrange for charge to be in motion and generate a useful magnetic field: We make a current flow through a wire, for example by connecting it to a battery.
