Question

What is the magnetic reluctance of a material that has a flux of 125mili Wb with a MMF of 180 AT​

Answer 1

Answer:

The formula for reluctance is: S = l/µ0 µr*A. From the formula, we can see that reluctance is directly proportional to the length of the material.

Explanation:

Answer 2

Concept:

The capacity of a magnetic substance to resist the movement of magnetic flux is known as reluctance. The field windings' magnetic flux travels along the path with the least magnetic resistance.

Any impact that seems to flow through or move through a surface or substance is referred to as a flux.

Given:

The flux of the material is $125$ milli weber.

The magnetomotive force is $180$ ampere-turn.

Find:

The magnetic reluctance of the material.

Solution:

The flux of the material is $125$ milli weber.

And mmf is $180$ AT.

Now,

the reluctance, R is the fraction of magnetomotive force and flux.

R = mmf/flux

$R=\frac{180}{125\times10^{-6} }$

$R=1440000$

The magnetic reluctance of the material is $1440000$ ampere-turn per weber.
