# Within The Solenoid, But Far From Its Ends, What Is The Magnetic Field B Due To The Current I?

## Within The Solenoid, But Far From Its Ends, What Is The Magnetic Field B Due To The Current I?

The magnetic field due to solenoid 1 passes (entirely, in this case) through solenoid 2, which has turns per unit length.

## What is the magnetic field at the ends of a solenoid?

The magnetic field at the ends of a very long current carrying solenoid is half of that at the center

## Why magnetic field at the end of the solenoid is half?

The magnetic field strength on the axis going right through the solenoid, in the place on the end of the solenoid is then the field of an infinitely long solenoid minus half of it because half is missing, and so the field strength is half as big on the ends (but right in the middle).

## What is the magnetic field at the Centre of the solenoid?

Thus, the magnetic field in the core of a solenoid is directly proportional to the product of the current flowing around the solenoid and the number of turns per unit length of the solenoid. This, the result is exact in the limit in which the length of the solenoid is very much greater than its diameter.

## Where the magnetic field of a solenoid is strongest?

The magnetic field is strongest inside the coil of a solenoid. Inside the coil of a solenoid, the magnetic field lines are uniform and tightly packed together which creates a stronger magnetic field here than anywhere outside of the solenoid.

## Is the strength of the magnetic field the same at all points inside a solenoid?

The magnetic field lines inside a current-carrying solenoid are parallel and equidistant which means the strength of the magnetic field is uniform inside the solenoid i.e. same at all points.

## What is a magnetic field due to current through a circular loop?

The magnetic field in a circular loop: The magnetic field lines are concentric circles at every point of a current-carrying circular loop. We can find the direction of the magnetic field of every section of the circular loop by using the right-hand thumb rule.

## What are the relation between the magnetic field at the center and the end of the solenoid?

Thus, the magnetic field at the center of a long solenoid is two times the magnetic field at the ends.

## How does currently affect magnetic field strength solenoid?

Adding more turns to the coil of the wire increases the strength of the field. Increasing the amount of current flowing through the coil also increases the strength of the magnetic field

## Why does the magnetic field of a long solenoid remain constant?

The magnetic field inside a long straight solenoid-carrying current is the same at all points. It is because the magnetic field in the solenoid is constant because the lines are completely parallel to each other.

## What is the formula of the magnetic field?

F=ILBsinθ where θ is the angle between the wire and the magnetic field. The force is perpendicular to the field and the current. The equivalent formula for the force on a moving charged particle of charge q and velocity v is F, equals, q, v, B, sine, theta, F=qvBsinθ, with the force perpendicular to field and velocity.

## Why is B non-zero outside the solenoid?

It’s pretty easy to show that the B-field goes to zero from a solenoid, even an infinite one, as the distance from the solenoid goes to infinity. And so the B-field has to be uniformly zero outside the solenoid.

## Where is the magnetic field zero in the solenoid?

At a point near the center outside the solenoid, the magnetic fields due to neighboring loops are equal in magnitude and opposite in direction. Hence the resultant magnetic field at a point near the center outside the solenoid is zero.

## Why magnetic field is uniform at all points inside a solenoid?

One end of the solenoid behaves as a magnetic north pole, while the other behaves as the South Pole. The field lines inside the solenoid are in the form of parallel straight lines. This indicates that the magnetic field is the same at all points inside the solenoid.

## Why the magnetic field within the ideal solenoid must be constant?

The force of a magnetic field is maximized when the current moves perpendicularly to the field lines, but is zero when it moves parallel to it; therefore, we can assume that in a solenoid the magnetic field is essentially uniform or constant because the wires are nearly parallel.
