# Why magnetic field lines are parallel in solenoid?

## Why magnetic field lines are parallel in solenoid?

Solenoid is made of no of turns of a wire, each turn makes a current loop, magnetic field near the centre of a loop appears by parallel lines,hence thease parallel line of force inside the core of solenoid represent combined magnetic fields.

## What is the direction of magnetic field lines inside the solenoid?

In a solenoid when direct current flows through it, one face of the solenoid becomes magnetic south pole and the second face becomes north pole. The magnetic field lines inside the solenoid run from the Magnetic South Pole to the Magnetic North Pole

## What does a solenoid do to the magnetic field around a wire?

A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside. Solenoids can convert electric current to mechanical action, and so are very commonly used as switches.

## Why are magnetic field lines parallel?

In a uniform magnetic field, the field lines are parallel equidistant straight lines. Following are the properties of the magnetic field: The magnetic field lines do not cross over each other. The strength of the field is proportional to the density of the lines.

## Why are the magnetic field lines straight and parallel inside a current carrying solenoid?

(c)The magnetic field lines inside a current-carrying solenoid are in the form of parallel straight lines. This pattern of field lines is indicating that the strength of the magnetic field is the same at all the points inside the current-carrying solenoid

## How are the magnetic field lines in a solenoid?

The magnetic field lines follow the longitudinal path of the solenoid inside, so they must go in the opposite direction outside of the solenoid so that the lines can form a loop. In order for the total number of field lines to be conserved, the field outside must go to zero as the solenoid gets longer.
