How is current related to magnetic field
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. Web18 feb. 2024 · The field from the magnet will induce a current only when it is increasing or decreasing. If you pull the magnet back out, it will again induce a current in the wire, but this time, it...
