# Difference between magnetic and electric circuits Difference between magnetic and electric circuits The distinction Between the Magnetic and electrical device are a unit explained considering numerous factors just like the basic definition, the relation between Flux and Current, Reluctance and Resistance, electromotive force, and MMF, totally different analogies of each the circuits. Like its density and intensity, laws applicable within the circuit, Magnetic and electrical lines, etc.

## Magnetic Circuit: The closed path followed by magnetic lines of forces or we can say magnetic flux is named magnetic circuit. A magnetic circuit is created from magnetic materials having high porousness like iron, soft steel, etc. Magnetic circuits square measure utilized in numerous devices like motors, transformers, relays, generator meters, etc.

## Electric Circuit: The transcription by that numerous electrical supplies like AC supply or DC source, resistances, capacitance and another electrical parameter square measure connected is named circuit or electrical network.

## Key variations Between Magnetic and electric circuits:

The closed path is followed by the flux within the Magnetic Circuit, whereas within the circuit Current follows the closed path. The unit of flux is Weber, and also the unit of current is Ampere.

The magnetomotive force within the magnetic circuit is the drive and is measured in Ampere-turns (AT). the electrical phenomenon is that the drive within the circuit is measured in volts (V).

In the magnetic circuit Permeance = 1/reluctance whereas within the circuit conductivity = 1/ resistance.

As within the magnetic circuit, there exists porousness thus a physical phenomenon within the circuit.

Similarly, physical property in a magnetic circuit is thought of as ohmic resistance within the circuit.

In the magnetic circuit, molecular poles square measure aligned. The flux doesn’t flow however sets up within the magnetic circuit. In a circuit electrical phenomenon flows within the style of electrons.

The reluctance (S) of a magnetic circuit isn’t constant rather it varies with the worth of B. The resistance (R) of an electrical circuit is nearly constant as its worth depends upon the worth. the worth and R will amendment slightly if the amendment in temperature takes place.

Once the magnetic flux sets up in a very magnetic circuit, no energy is distended. solely a little quantity of energy is needed at the initial stage to make flux within the circuit. Energy is increasing unendingly, as long as the current flows through the electric circuit.

## This energy is dissipated within the style of heat.

Kirchhoff flux and MMF law are followed within the magnetic circuit whereas within the circuit G. R. { kirsch off| Gustav Robert Kirchhoff physicist} voltage and the current law are followed. (KVL and KCL).
Magnetic lines of flux begin from The North Pole and end at the South Pole. electrical lines or current start from the charge and end on the electric charge.
