Flux density in magnetic circuit

  1. Sep 26, 2013 #1
    1. The problem statement, all variables and given/known data
    Consider the magnetic circuit shown in figure 3
    Assuming that the core (μr=1000) has a uniform cross section of 4 cm^2, determine the flux density in the air gap the picture is very small so here are the values L=42cm, Ig=0.1cm, turns=500, and I=0.2A


    2. Relevant equations
    Flux=magnetomotive force/reluctance or NI/((L/μ0(μr)A)+(G/Aμ0))


    3. The attempt at a solution
    When I plug the values given in the problem statements and figure 3. I get .000035493 I am not sure of the units however?
