What is the analogous value of resistance in magnetic circuit?

The reluctance of a magnetic circuit is analogous to the resistance of an electric circuit. Reluctance depends on the geometrical and material properties of the circuit that offer opposition to the presence of magnetic flux.

What is analogous to current in the magnetic circuit?

Reluctance. Magnetic reluctance, or magnetic resistance, is analogous to resistance in an electrical circuit (although it does not dissipate magnetic energy).

What is analogous to Permeance?

Permeance is a measure of the quantity of magnetic flux for a number of ampere - turns. It is the reciprocal of reluctance. It is analogous to conductance.

What is analogy of electric circuit?

In this analogy a circuit is modelled as a big loop of rope. One person is the battery and pulls the loop through their hands. Another person is the resistance and squeezes the rope. Friction with the hands of the resistor person means they can feel the energy transferred as heat.

What is analogous to conductance?

Permeance is a magnetic property, it is analogous to conductance.

Is analogous to conductivity?

Conductivity is analogous to Magnetic Circuit.

What is an analogy for current?

When describing voltage, current, and resistance, a common analogy is a water tank. In this analogy, charge is represented by the water amount, voltage is represented by the water pressure, and current is represented by the water flow. So for this analogy, remember: Water = Charge.

What are the analogous quantities in magnetic and electric circuits?

The magnetic flux is analogous to the electric current. The magnetomotive force, mmf, is analogous to the electromotive force and may be considered the factor that sets up the flux. The mmf is equivalent to a number of turns of wire carrying an electric current and has units of ampere-turns.

What is reluctance in magnetic circuit?

The reluctance of a magnetic circuit is analogous to the resistance of an electric circuit. Reluctance depends on the geometrical and material properties of the circuit that offer opposition to the presence of magnetic flux.

What is the reciprocal of reluctance?

Permeance is the reciprocal of reluctance is a measure of magnetic flux for a number of current turns in a magnetic circuit. The SI unit of magnetic permeance is Weber per ampere-turn that is H (henry). Permeance is the measure of the ease with which flux can be set up in a material.

What is H in magnetic circuit?

H is the magnetic field produced by the flow of current through the wire. The expression for H can be written as H = (B/µ) – M. B is the magnetic flux density. µ is the magnetic permeability. M is the magnetization.

What remains same in parallel magnetic circuit?

We have seen that a series magnetic circuit carries the same flux and the total mmf required to produce a given quantity of flux is the sum of the mmf' s for the separate parts. In a Parallel Magnetic Circuit, different parts of the circuit are in parallel.

What is the unit of reluctance?

Reluctance(S) is the property of a magnetic circuit opposing the passage of magnetic flux lines, equal to the ratio of the magnetomotive force to the magnetic flux. It is measured in AT/weber. The unit of reluctance is ampere-turns per weber i.e., (Henry)^-1.

Which is the equation of magnetomotive force?

Magnetomotive force (mmf), F_m = NI ampere-turns (At), where N = number of conductors (or turns) and I = current in amperes.

What happens to the MMF when the magnetic flux decreases?

Ohm's law for magnetic circuit's states that the MMF is directly proportional to the magnetic flux hence as the magnetic flux decreases, the MMF also decreases.

What is reluctance and Reluctivity?

Reluctivity is the property of a substance; reluctance is the property of a circuit.

What is the unit of magnetomotive force?

The standard unit of magnetomotive force is the ampere-turn (AT), represented by a steady, direct electrical current of one ampere (1 A) flowing in a single-turn loop of electrically conducting material in a vacuum . Sometimes a unit called the gilbert (G) is used to quantify magnetomotive force.

What do you mean by leakage flux?

The part of magnetic flux that does not follow the desired path in a magnetic circuit is known as leakage flux. In most of practical magnetic circuits, the path of a large part of the magnetic flux is through iron part of the magnetic circuit and the rest part of magnetic flux flows through air.

What is relative permeability compare between magnetic and electric circuits?

In the magnetic circuit Permeance = 1/reluctance whereas in the electric circuit Conduction = 1/ resistance. As in the magnetic circuit, there exists Permeability so as Conductivity in the electric circuit. Similarly, Reluctivity in magnetic circuit is known as Resistivity in the electric circuit.
