## How can we find the direction of field of solenoid?

To do this, point your right thumb in the direction that the current travels in the coiled wire in the solenoid and curl your fingers. * The direction your fingers point will determine the direction of the magnetic field created by the current. Alternately the right-hand-grip rule is easier to use with solenoids.

### What is the direction of field lines inside a current carrying solenoid?

The correct answer is parallel straight lines. The magnetic field lines inside a solenoid are in the form of parallel straight lines.

Does solenoid have direction?

If the direction of current is anti-clockwise, the end of the solenoid acts as a north pole and vice-versa.

Which is north and south in solenoid?

The end of the current carrying solenoid at which the current flows anti clock wise behaves as a north pole while that end at which the direction of current is clockwise behaves as a south pole and this is according to clock wise.

## What direction is magnetic field?

moving charge is perpendicular to the direction of motion. The direction of the force due to a magnetic field is perpendicular to the direction of motion.

### Why the magnetic field lines inside the solenoid are parallel?

The magnetic field lines in the middle of a current-carrying solenoid are parallel to the axis of the tube because the magnetic field is uniform inside a solenoid.

Is magnetic field inside a solenoid zero?

magnetic field inside a solenoid is uniform as the lines move from north to south in a uniform manner with same magnitude without giving any diflection except for the fact that magnetic fields are stronger near the poles.

Is magnetic field inside a solenoid uniform?

Inside a solenoid the magnetic field lines will be straight lines and the field will be strong. Outside the solenoid the magnetic field will be weak and the field lines will curl up to form closed loops. Hence, the magnetic field inside a solenoid will be uniform.

## Which end of the solenoid is the north pole?

(a) The end of the solenoid at which current flows in the anticlockwise direction will act as a north pole and the end where current flows in clockwise direction will act as a south pole. (b) The magnetic field produced in a current carrying solenoid is similar to that produced by a bar magnet.

### Does current flow from north to south in a solenoid?

This is NOT an electromagnetic induction question. The current flows in the clockwise direction at the south pole and in the anticlockwise direction at the north pole, in both coils, so the ‘S and N rule’ is not broken.]

Is magnetic field directed from north to south?

19.2 Magnetic Field of the Earth The Earth has a magnetic field of its own. The north pole of a magnet is attracted to the North magnetic pole of the Earth, and the south pole to the South magnetic pole, hence the choice of north and south for designating the poles of a magnet.

How is direction of electron movement is determined in solenoid?

The direction of the wrapping of the coil winding matters, not the flow from “top to bottom” or “left to right”. When you use the left hand rule, your fingers should point in the direction that the current is flowing in the wires making up the turns on the side of the coil where your fingers make contact.

## Why magnetic field inside the solenoid is uniform?

As the current flowing through the loops in solenoid carry same amount of current, the field lines produced by individual loops join/augment each other to produce uniform magnetic field.

### What is the nature of magnetic field inside the solenoid?

Solution : (a) The magnetic field lines inside a current-carrying solenoid are parallel to its axis. (b) Near the centre of the coil, the magnetic field lines are nearly straight and parallel. Near the coil, the magnetic field lines are nearly circular and cocentric.

What is the direction of the magnetic lines of force inside the magnet?

The direction of magnetic lines of force of a bar magnet is from north to south pole outside the magnet and from south pole to north pole inside the magnet as shown in figure.

What is the direction of magnetic field outside the 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.

## Why magnetic field inside a solenoid is uniform and parallel?

Magnetic fields inside the solenoid is uniform because magnitude remain equal and direction of magnetic field remain same at each point of solenoid. The wires in solenoid are parallel which allows uniform magnetic field and and is directed along the axis of the solenoid. Hence, the correct answer is uniform.

### Does magnetic field flow from north to south?

Magnetic fields may be created with magnetic materials. A magnet has a North and a South Pole. A magnetic field flows from the North to the South Pole in the same way that electric fields flow from positive to negative charges. However, once cannot isolate magnetic poles as one can isolate electric charges.

How does current flows in a solenoid?

The current flows in the clockwise direction at the south pole and in the anticlockwise direction at the north pole, in both coils, so the ‘S and N rule’ is not broken.]

What is the direction of magnetic field?

## What direction does the magnetic field go?

Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.

### What is the direction of the magnetic field with respect to the current of a solenoid Mcq?

What is the direction of the magnetic field with respect to the current of a solenoid? Explanation: The direction of the magnetic field generated in a solenoid acts always perpendicular to the direction of the applied current.

What is magnetic field direction?

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.

Where is magnetic field strongest in a solenoid?

a long tightly wound helical coil insulated metallic wire is called solenoid.

• the magnetic field produce inside the solenoid ( also called core of solenoid ) is Constant.
• a circular solenoid is called toroid.
• the strength of magnetic field increase if current flowing in solenoid increase.
• ## Why is the magnetic field outside a solenoid considered zero?

The magnetic field lines exist outside the solenoid, but the number of field lines per unit area outside the solenoid is much less compared to the number of lines per unit area inside the solenoid. Hence the magnetic field outside is so feeble that it is considered to be practically zero.

### What is magnetic field outside the solenoid?

The magnetic field is defined to be the spacial density of the flux lines. The volume of space outside of the solenoid is infinitely large so the spacial density of the flux lines (field strength) IS equal to zero outside of the solenoid. 383 views

How can you strengthen a solenoid’s magnetic field?

By inserting a core within a coil , the power of the magnetic field can be increased. When you put a ferrous (iron) core inside a solenoid, the magnetic field lines are concentrated and therefore strengthen the magnetic field. The magnetic flux is defined as the number of magnetic field lines that pass through a given area.
