How does diameter affect solenoid?

Larger the outer diameter and greater the length of the solenoid, more turns of the conductor can be accommodated. But this will increase the resistance of the coil. If you have a fixed voltage source, the gain in turns is offset by the increase in resistance.

How does the magnetic field set up in a solenoid changes when a diameter of the solenoid is increased?

a When number of turns are increased magnetic field will be stronger. b When diameter of the solenoid is increased but diameter should be less than the length of solenoid so that parallel lines should add up to give a stronger field. c When strength of current is increased stronger will be the magnetic field produced.

How does the diameter of the coil loop affect the magnetic field?

Yes,rather higher diameter of coil would consume more material causing,more hysteresis loss,thereby decrease the magnetic induction.So to the magnetic field. The diameter of the magnet wire only indirectly affects a solenoid’s field strength.

How is the magnetic field inside a solenoid depends upon the number of turns?

The number of turns in the solenoid-Larger the number of turns in the solenoid, greater will be the magnetism produced. The strength of current in the solenoid-Larger the current passed through the solenoid, stronger will be the magnetic field.

How does a magnetic field set up by a solenoid?

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. The energy density of the magnetic field depends on the strength of the field, squared, and also upon the magnetic permeability of the material it fills.

How does the magnetic field set up by a solenoid change when the number of turns of the coil are increased?

By having more number of turns, the intensity of magnetic field increases.

Does diameter affect magnetic field?

The magnetic field inside a solenoid is proportional to both the applied current and the number of turns per unit length. There is no dependence on the diameter of the solenoid, and the field strength doesn’t depend on the position inside the solenoid, i.e., the field inside is constant.

What happens to the induced emf in a loop if the area of the loop doubles?

A. The induced emf is four times as much. The magnetic flux is proportional to the area, which will increase by a factor of four when the diameter is doubled.

On what factors does the magnetic field around a solenoid depends upon?

1. The strength of current in the solenoid: Larger the current passed through solenoid, stronger will be the magnetic field produced. 2. The number of turns in the solenoid: Larger the number of turns in the solenoid, greater will be the magnetic field produced.

On what factors magnetic field of solenoid depends?

The magnetic field within a solenoid depends upon the current and density of turns. The energy density of the magnetic field depends on the strength of the field, squared, and also upon the magnetic permeability of the material it fills.

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.

Where is the magnetic field uniform in a solenoid?

The ‘uniform’ magnetic field within a long solenoid is parallel to the solenoid axis. Its direction along the axis is given by a curled-straight right-hand rule.

Why magnetic field outside the solenoid is zero?

However, the volume outside the solenoid is much greater than the volume inside, so the density of magnetic field lines outside is greatly reduced . Now recall that the field outside is constant. In order for the total number of field lines to be conserved , the field outside must go to zero as the solenoid gets longer.

How can the magnetic field around a solenoid be strengthened?

The strength of the magnetic field around a solenoid can be increased by: increasing the number of turns on the coil increasing the current placing an iron core inside the solenoid
