| Path traced by the current is known as electric current. | Path traced by the magnetic flux is called as magnetic circuit. |
| EMF is the driving force in the electric circuit. The unit is Volts. | MMF is the driving force in the magnetic circuit. The unit is ampere turns. |
| There is a current I in the electric circuit which is measured in amperes. | There is flux φ in the magnetic circuit which is measured in the weber. |
| The flow of electrons decides the current in conductor. | The number of magnetic lines of force decides the flux. |
| Resistance (R) oppose the flow of the current. The unit is Ohm |
Reluctance (S) is opposed by magnetic path to the flux. The Unit is ampere turn/weber. |
| R = ρ. l/a. Directly proportional to l. Inversely proportional to a. Depends on nature of material. |
S = l/ (μ0μra). Directly proportional to l. Inversely proportional to μ = μ0μr. Inversely proportional to a |
| The current I = EMF/ Resistance | The Flux = MMF/ Reluctance |
| The current density | The flux density |
| Kirchhoff current law and voltage law is applicable to the electric circuit. | Kirchhoff mmf law and flux law is applicable to the magnetic flux. |
