How is current related to flux?

It states that current induced opposes the magnetic field. So, a change in flux induces a current and a voltage which is proportional to the rate of change of flux. This fits with Ohm’s Law (V = IR). A current and a voltage in a coil induce a flux which is proportional to the current and the voltage.

Is flux and current same?

Current is rate of flow of Electric charge through any given area. Electric flux, Φ = ∫∫ E Δs = Q/ε = i Δt/ε where i is current. Flux is directly proportional to current. Due to the flow of charge current forms as well as due the charge flux is produced around the charge.

What is the relation between magnetic flux and 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 flux when current is zero?

Due to which an emf is induced in the other coil and as the loop is closed, current starts flowing which is being driven by the induced force. Hence, if a current is zero means the flux linkage and the flux is zero.

What is current flux?

In Electromagnetism, the electric field is defined as the measure of the flow of electric current through a given area. Electric flux is the rate at which the electric field flows through a given area. The electric flux is directly proportional to the number of electric field lines going through the virtual surface.

What is a flux current?

Flux current, simplistically described, is the portion of the total current which magnetizes the motor. The Power Factor will also improve as it is an expression of the phase angle between the voltage and the current.

Why change in magnetic flux produces current?

To read magnetic data, the ferromagnetic material is moved past the coil of wire. The changing magnetic field caused by the material’s motion induces a current in the coil of wire proportional to the change in field.

How do you know if flux is increasing or decreasing?

If the magnetic flux is increasing, then that implies the induced magnetic field points in the opposite direction of external magnetic field. On the other hand, if the magnetic flux is decreasing, the two fields will point in the same direction.

Is current a flux?

Given a current such as electric current—charge per time, current density would also be a flux according to the transport definition—charge per time per area.

Why does the current become zero while the loop is fully enclosed?

While the loop is fully inside the magnetic field, there is no flux change and therefore no induced current.

What is electric flux equal to?

The total of the electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux through an area is defined as the electric field multiplied by the area of the surface projected in a plane perpendicular to the field.
