Web12 sep. 2024 · The magnetic field is directed in the counterclockwise direction for the windings shown. When the current in the coils is reversed, the direction of the magnetic field also reverses. The magnetic field inside a toroid is not uniform, as it varies inversely with … WebWhat is toroid formula? Magnetic Field of Toroid The toroid is a useful device used in everything from tape heads to tokamaks. Magnetic field = permeability x turn density x current. For a solenoid of radius r = m with N = turns, the turn density is n=N/(2πr)= turns/m.
