Question

what are the similarities and dissimilarities between magnetic and electric circuit?​

Answer 1

Similarities:

1. The close path for the magnetic flux is called magnetic circuit. The close path for the electric current is called electric circuit.
2. The number of magnetic lines of force decide the magnetic flux. Flow of electron decide the current passing through the conductor.
3. Flux (ф) = MMF/Reluctance Current (I) = EMF/Resistance

Dissimilarities:

1. Magnetic flux does not flow but it set up in the magnetic circuit. The electric current actually flows in an electric circuit.
2. At constant temperature, the reluctance (S) of a magnetic circuit is not constant but varies with μr. At constant temperature, the resistance of an electric circuit is constant as its value depends on resistivity which is almost constant.
3. Once magnetic flux is setup in a magnetic circuit, no energy needed. Energy needed as long as current flows through electric circuit.
