What is reluctance of magnetic circuit?

Magnetic reluctance (also known as reluctance, magnetic resistance, or a magnetic insulator) is defined as the opposition offered by a magnetic circuit to the production of magnetic flux. It is the property of the material that opposes the creation of magnetic flux in a magnetic circuit.

What is the reluctance of a magnetic material?

Magnetic reluctance, or magnetic resistance, is a concept used in the analysis of magnetic circuits. It is defined as the ratio of magnetomotive force (mmf) to magnetic flux. It represents the opposition to magnetic flux, and depends on the geometry and composition of an object.

What is reluctance in magnetic materials Mcq?

Explanation: Reluctance, as the name suggests, is something which is reluctant or hesitant to do. As per the magnetic terms it resists the building up of magnetic flux in the materials. 10.

How does the reluctance of air in a magnetic circuit compare with the resistance of air in an electric circuit?

Reluctance opposed the flow of magnetic flux S = l/aµ and measured in (AT/wb) and Resistance opposes the flow of current R = ρ. l/a and measured in (Ώ). In the magnetic circuit Permeance = 1/reluctance whereas in the electric circuit Conduction = 1/ resistance.

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). The permeance is analogous to the conductance in an electrical circuit.

What is the symbol for reluctance?

The ‘magnetic resistance’ of a magnetic circuit to the presence of magnetic flux is called reluctance. The symbol for reluctance is S (or Rm). The unit of reluctance is 1/H (or H-1) or At/Wb.

Which of the following is the reciprocal of the reluctance?

Permeance
Permeance is the reciprocal of reluctance is a measure of magnetic flux for a number of current turns in a magnetic circuit.
