How do you define magnetic flux density at any point?
Magnetic Flux Density is amount of magnetic flux through unit area taken perpendicular to direction of magnetic flux. Flux Density (B) is related to Magnetic Field (H) by B=μH.
What does the constant U indicate while specifying the relation between magnetic flux density B and magnetic field intensity H?
Magnetic flux linked with a surface is maximum when area is held perpendicular to the direction of field. Here, µ is the permeability of the medium and ‘H’ is magnetic intensity, i.e., the number of lines of force per unit area in free space.
What is the relation between flux density and vector potential?
Explanation: The magnetic flux density B can be expressed as the space derivative of the magnetic vector potential A. Thus B = Curl(A).
What is the relationship between magnetic flux density and magnetic field strength?
so that the value of the field intensity, H, is directly proportional to the value of induced flux density, B (or B-field), and the term “magnetic field intensity” is then often loosely used for both the H-field and the B-field.
How is magnetic flux density measured?
Assuming the magnetic field distributed uniformly inside the rod, then we can calculate the magnetic flux density B by dividing the total magnetic flux by the cross sectional area of the rod.
How do you calculate magnetic flux density?
The equation for calculating the force on a wire is Force (N) = magnetic flux density (T) × current (A) × length (m) or, in short F = B I L.
What is relation between magnetic flux and magnetic induction?
magnetic flux: A measure of the strength of a magnetic field in a given area. induction: The generation of an electric current by a varying magnetic field.
What is the relation between magnetic field and magnetic flux?
Magnetic field describes a region where a magnetic force can be felt. Magnetic flux describes how much magnetic field passes through an area.
What is the relation between magnetic induction B and vector potential?
The more frequently used magnetic vector potential is defined so that its curl is equal to the magnetic field: curl A = B. Together with the electric potential φ, the magnetic vector potential can be used to specify the electric field E as well.
How do you calculate magnetic flux density from a magnetic vector potential?
The magnetic flux density B and the vector magnetic potential A are related as
- B = ∇ × A.
- A = ∇ × B.
- B = ∇ ⋅ A.
- A = ∇ ⋅ B.
