Whats Ohms law equivalent in magnetic fields?

  I am unaware of an equivalent law.
  Maybe Ampere's law relating Magneto motive force to the number of turns in a coil and the current can be considered:
  (MMF) = N x I (N- number of turns in coil and I current in coil)
  This is similar to Ohm's law
  (EMF) = R x I
  
  Any physics CEans may come up with something better.

  thanku sir,but i found Rowland's law is magnetic ohms law equivalent which states the same.
