# Addition of Reluctances in Parallel [MAGNETISM]

• Ghost101
In summary, the conversation discusses the topic of reluctance in magnetic circuits and its similarities to electric circuits. It is mentioned that when the core is in a "series" network, the reluctances are added together, but the question arises if this also applies when the core is split into multiple "loops". The individual's logic suggests that the rules of parallel addition do not apply for a core. Overall, it is stated that reluctance works similarly to resistance in both series and parallel.

## Homework Statement

Hey guys,

I have an incredibly broad question, just revising the topic of Magnetism,

On the topic of reluctance,
As I have learned so far, Magnetic Circuits and electric circuits have similar properties.

When the core is a "series" network, you add Reluctance together,

R(t) = R1 + R2 + ... etc

when the core is split into more than one "loop" do we still add reluctance like we do in series?

My logic would say that the rules of parallel addition of resistors doesn't apply for a core.

## What is the concept of "addition of reluctances" in magnetism?

The addition of reluctances refers to the process of calculating the total reluctance in a circuit that contains multiple parallel paths. Reluctance is a measure of the resistance to magnetic flux in a material or circuit.

## Why is the addition of reluctances important in magnetism?

In magnetism, the total reluctance in a circuit is crucial in determining the overall flow of magnetic flux. It allows us to understand the behavior of magnetic fields and design efficient circuits for various applications.

## What is the equation for calculating the total reluctance in parallel paths?

The equation for calculating the total reluctance in parallel paths is RT = 1/(1/R1 + 1/R2 + ... + 1/Rn), where R1, R2, ... , Rn are the reluctances of each individual path.

## How does the addition of reluctances affect the overall magnetic flux in a circuit?

The addition of reluctances in parallel paths results in a decrease in the overall reluctance, which increases the flow of magnetic flux in the circuit. This allows for a stronger and more efficient magnetic field.

## Can the concept of addition of reluctances be applied to circuits with series paths?

No, the concept of addition of reluctances only applies to circuits with parallel paths. In series circuits, the reluctances are added together to calculate the total reluctance, as opposed to the inverse sum in parallel circuits.
