Permeance Solution

Follow our step by step solution on how to calculate Permeance?

FIRST Step Consider the formula

P = \frac{1}{S}

Next Step Substitute values of Variables

∴

P = \frac{1}{0.61AT/Wb}

Next Step Prepare to Evaluate

∴

P = \frac{1}{0.61}

Next Step Evaluate

∴

P = 1.63934426229508H

LAST Step Rounding Answer

∴

P = 1.6393H

Magnetic Permeance

Magnetic Permeance is defined as the reciprocal of reluctance in a magnetic circuit.

Symbol: P

Measurement: InductanceUnit: H

Note: Value can be positive or negative.

Formulas to find Magnetic Permeance

Reluctance

The reluctance of a magnetic material is its ability to oppose the flow of magnetic flux. The magnetic flux created by the field windings follows the path of least magnetic reluctance.

Symbol: S

Measurement: ReluctanceUnit: AT/Wb

Note: Value should be greater than 0.

How to Evaluate Permeance?

Permeance evaluator uses Magnetic Permeance = 1/Reluctance to evaluate the Magnetic Permeance, The Permeance formula is defined as the inverse of reluctance. In a magnetic circuit, permeance is a measure of the quantity of magnetic flux for a number of current-turns. Magnetic Permeance is denoted by P symbol.
