How is magnetic flux density related to current?

Sample Answer: The magnetic flux density through a coil is directly proportional to current. When the current increases the magnetic flux density will increase.

What is the rule of magnetic flux density?

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. It is measured in Webers per square meter equivalent to Teslas [T].

What is flux density in magnetic circuit?

The magnetic flux density or magnetic induction is the number of lines of force passing through a unit area of material, B. The unit of magnetic induction is the tesla (T).

How do the current and electric field related to the change in magnetic flux?

It states that the direction is always such that it will oppose the change in flux which produced it. This means that any magnetic field produced by an induced current will be in the opposite direction to the change in the original field.

How does current affect magnetic flux?

Current is directly proportional to magnetic force for a straight current carrying conductor in a uniform magnetic field. So the force is directly proportional to the size of the current. Practically this means the following: If the current is doubled the force on the conductor will double.

What is the formula for electric flux density?

The electric flux density D=ϵE, having units of C/m2, is a description of the electric field in terms of flux, as opposed to force or change in electric potential.

What is magnetic flux density with example?

magnetic flux density. A vector quantity measuring the strength and direction of the magnetic field around a magnet or an electric current. Magnetic flux density is equal to magnetic field strength times the magnetic permeability in the region in which the field exists.

What is the relationship between magnetic flux and magnetic flux density?

The magnetic flux in a constant magnetic field can be expressed mathematically as, ɸ = B.S. ɸ is magnetic flux through the vector surface, B is the magnetic flux density and S is the area of the surface.

Why change in magnetic flux produces current?

When an emf is generated by a change in magnetic flux according to Faraday’s Law, the polarity of the induced emf is such that it produces a current whose magnetic field opposes the change which produces it. The induced magnetic field inside any loop of wire always acts to keep the magnetic flux in the loop constant.
