Magnetic field of a solenoid calculator

Magnetic field in a solenoid formula is given as B = μ0 nl. In the formula, B represents the magnetic flux density, μ0 is the magnetic constant whose value is 4π x 10-⁷ Hm or 12.57 x 10−⁷ Hm, N represents the number of turns, I is the current flowing through the solenoid.

What is the magnetic field of a solenoid?

The magnetic field generated by the solenoid is 8.505 × 10−4 N/Amps m.

How do you calculate magnetic field?

The magnitude of the force on a wire carrying current I with length L in a magnetic field is given by the equation. F=ILBsinθ where θ is the angle between the wire and the magnetic field.

What is the magnetic field at the end of a solenoid?

Assertion :The magnetic field at the ends of a very long current carrying solenoid is half of that at the centre. Reason: If the solenoid is sufficiently long, the field within it is uniform.

Why the magnetic field is equal in solenoid?

Bar magnet and solenoid both have attractive and directive properties ie, to align itself along the external magnetic field. The magnetic field at the axial point is the same for both. The magnetic moment is the same for both.

Where is magnetic field zero in a solenoid?

Points at which resultant magnetic field is zero are called neutral points. This is because the magnetic field produced by the magnet is neutralised by some other equal and opposite magnetic field. This other magnetic field is an actually horizontal component of earth's magnetic field.

How do you calculate the force of a solenoid?

Formula: F = (n x i)2 x magnetic constant x a / (2 x g2) Where, F = Force, i = Current, g = Length of the gap between the solenoid and a piece of metal, a = Area n = Number of turns, Magnetic constant = 4 x PI x 10-7.

Why magnetic field of solenoid is half of end?

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).

Why magnetic field inside the solenoid is maximum?

The net magnetic field is the sum from each individual loop and is maximum in the middle of the solenoid because that point minimizes the average distance to each loop.

Is magnetic field inside a solenoid always zero?

If the solenoid is very long than it is more true to consider magnetic field outside the solenoid to be zero. Near the edge of the solenoid it is not true. For practical purpose we take magnetic field outside the solenoid to be zero.

Does magnetic field depend on length of solenoid?

The magnetic field of solenoid is directly proportional to the current passing and the number of turns and has a proportionality constant which depends on material of conductor, instead of area magnetic field depends upon the length of solenoid.

Why is the magnetic field at neutral zero?

The forces due to both magnets cancel each other, i.e. there is no net force. Hence, at a neutral point, the resultant magnetic force is zero.

Where is the highest magnetic field in a solenoid?

Answer and Explanation: 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 magnetic field inside a solenoid infinite?

Magnetic fields of finite and infinite solenoid An infinite solenoid is given by the superposition of two facing semi-infinite solenoids. The field inside an infinite solenoid is constant and parallel to its axis and does not vary across the radius of the solenoid.

What is the rule for solenoid?

An electric current passes through a solenoid, resulting in a magnetic field. When you wrap your right hand around the solenoid with your fingers in the direction of the conventional current, your thumb points in the direction of the magnetic north pole.

Which rule is used for solenoid?

The second right-hand rule establishes the relationship between the direction of the magnetic field and the direction in which the electric current moves in a solenoid.

Does increasing length of solenoid affect the magnetic field?

The radius and the length don't directly affect the field, they affect indirectly the ampere turns . 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.

What is the unit of N in solenoid?

This is an Expert-Verified Answer n refers to the number of turns per unit length.

What factors affect the magnetic field of a solenoid?

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.

What affects the magnetic field of a solenoid?

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.
