magnetic field strength
Give the relation between magnetic field strength, magnetic flux density and permeability.
Define magnetic field strength and state its unit. Answer : Magnetic field strength is the force experienced by a unit N-pole when placed at any point in a magnetic field is known as magnetic field strength or magnetizing force. Magnetising force or magnetic field ... unit of length is metre. So the unit of magnetic field strength is ampere turns per metre....
An iron ring of mean circumference 80 cm is uniformly wound with 500 turns of wire and carries 0.8A. Find the magnetic field strength. Answer : Ans: Magnetic field strength H = NI /l = 500 x 0.8 / 80 x 10-2 = 500 AT/m ...
