# TOTAL FLUX through a solenoid

• K Dhiraj Bhak
In summary, a solenoid is an electromagnet that creates a magnetic field when an electric current is passed through it. The total flux through a solenoid is directly proportional to the number of turns in the coil and can be affected by factors such as the strength of the current, the material of the core, and external magnetic fields. Reversing the direction of the current also changes the direction of the magnetic field and the total flux.

suppose a solenoid has N turns
What is the Flux through the Solenoid?

similarly if a coil has N turns , what is the flux through the whole coil?
i know how to find flux through a given AREA,,,like a coil with just 1 turn...

How do u find flux for the entire system?

Superposition principle: you add up the flux from each turn.

ok, thanks!

## What is a solenoid?

A solenoid is a type of electromagnet that consists of a wire coiled into a cylindrical shape. When an electric current is passed through the wire, it creates a magnetic field.

## What is the total flux through a solenoid?

The total flux through a solenoid is the measure of the strength of the magnetic field passing through the coil. It is calculated by multiplying the magnetic field strength by the area of the coil.

## How is the total flux through a solenoid affected by the number of turns in the coil?

The total flux through a solenoid is directly proportional to the number of turns in the coil. This means that increasing the number of turns will result in a stronger magnetic field and therefore a higher total flux.

## How does the direction of the current affect the total flux through a solenoid?

The direction of the current in a solenoid determines the direction of the magnetic field. This, in turn, affects the direction of the total flux through the solenoid. Reversing the direction of the current will also reverse the direction of the magnetic field and the total flux.

## What factors can affect the total flux through a solenoid?

The total flux through a solenoid can be affected by the strength of the current, the number of turns in the coil, and the material of the core of the solenoid. It can also be affected by external magnetic fields or the presence of nearby conductors.
