Question

What is the similarity in magnetic circuits fix conductance in electrical circuit?

Hola mate✨✨✨
I've got ur answer ✨



Due to mmf flux gets established and does not flow in the sense in which current flows.There are many materials which can be used as insulators  (air, PVC, synthetic resins etc) which current can not passThere is no magnetic insulator as flux can pass through all the materials, even through the air as well.Energy must be supplied to the electric circuit to maintain the flow of current.Energy is required to create the magnetic flux, but is not required to maintain it.The resistance and conductivity are independent of current density under constant temperature. But may change due to the temperature.The reluctance, permanence and permeability are dependent on the flux density.Electric lines of flux are not closed. They start from positive charge and end on negative charge.Magnetic lines of flux are closed lines. They flow from N pole to S pole externally while S pole to N pole internally.There is continuous consumption of electrical energy.Energy is required to create the magnetic flux and not to maintain it.
