I What exactly is Reluctance?

  1. Jun 30, 2016 #1
    Electrical resistance is due to electrons colliding with the atoms of the conductor. In a magnetic circuit reluctance is analogous to resistance in an electric circuit. Just as resistance impedes the flow of electrons in an electric circuit, reluctance impedes the flux in a magnetic circuit but how does it do this? Since flux is the magnetic field lines per unit area how does the material increase or lower the number of field lines.

    It is easier to magnetize (create a magnetic flux in) some materials than others. As Wikipedia says.. "Air and vacuum have high reluctance, while easily magnetized materials such as soft iron have low reluctance".
