A magnet field is the area surrounding a magnet within which the effects of that field may be observed.
A magnetic field is represented by imaginary lines of force that we call magnetic flux. Magnetic flux (symbol, the Greek letter phi) is measured in webers (pronounced 'vay-bers'); the intensity of the magnetic flux is called magnetic flux density which is defined as the flux per unit area, measured in webers per square metre, which is given the special name, the tesla.

∙ 8y agoElectric flux is corresponding to the quantity of electric field lines going through a surface perpendicular to the lines. More generally, in the event that the electric field is uniform, the electric flux going through a surface is ES cos theta, where S is the area of the surface, E is the magnitude of the electric field and theta is the angle between the field lines and the normal to the surface.
Magnetic flux is the quantity of magnetic field lines going through a closed surface. The SI unit of attractive flux is the weber (Wb). The CGS unit is the maxwell.

∙ 11y agothe relation between magnetic flux density and applied voltage is proportional..that is why it is said that eddy current loss is proportional to square of the supply voltage

What is the difference between magnetic flux magnetic flux densitymagnetic flux linkage?
light speeeed mofos
How does an electric generator works?
The voltage was produce by cutting of the magnetic flux by the conductors.
How the voltage is induced in a single phase transformer?
The changing magnetic flux in the iron core of the transformer induces a voltage in the windings.
When lines of force are cut by what you have electromagnetic induction?
When magnetic flux lines of force are cut by induced voltage between magnetic and electric currents. Electromagnetic induction is created.
Why voltage induced when moving coil cuts flux?
The magnetic flux passing the coil changes by its rotation thus induced emf is produced and induced current flows
What is a bh curve?
A graph showing the relation between the magnetic flux density B and the magnetizing force H , for a magnetic material.
What are the two main types of flux?
Types of flux - Electric and Magnetic Flux. Electric field flux through a closed surface is equal to the change enclosed in the surface, or the rate of change of magnetic flux is equal to the induced voltage around the surface.

What is the relation of conductor velocity?
The conductor velocity is directly related to the induced voltage in a conductor moving through a magnetic field. This relationship is described by Faraday's law of electromagnetic induction, which states that the induced voltage is proportional to the rate of change of magnetic flux through the conductor.
How does an electric generator works?
The voltage was produce by cutting of the magnetic flux by the conductors.
Which law states that voltage is induced in a circuit whenever the flux linking the circuit is changing and that the magnitude of the voltage is proportional to the rate of change of the flux linkage?
Faraday's law of electromagnetic induction states that a voltage is induced in a circuit whenever there is a changing magnetic field that links the circuit, and the magnitude of the induced voltage is proportional to the rate of change of the magnetic flux.
How the voltage is induced in a single phase transformer?
The changing magnetic flux in the iron core of the transformer induces a voltage in the windings.
When lines of force are cut by what you have electromagnetic induction?
When magnetic flux lines of force are cut by induced voltage between magnetic and electric currents. Electromagnetic induction is created.
What flux that does not follow the intended path in a magnetic circuit?
Leakage flux is the flux that does not follow the intended path in a magnetic circuit. It represents the magnetic field that strays outside of the core and does not contribute to the desired magnetic coupling between the components of the circuit. Strategies such as improving the design and materials of the magnetic circuit can help minimize leakage flux.
What does the rate of change of flux equal?
The rate of change of flux equals the induced electromotive force or voltage in a circuit, as described by Faraday's law of electromagnetic induction. Mathematically, this relationship is expressed as: (\text{EMF} = -\frac{d\Phi}{dt}), where EMF is the induced voltage, (\Phi) is the magnetic flux, and (\frac{d\Phi}{dt}) is the rate of change of magnetic flux over time.
Why voltage induced when moving coil cuts flux?
The magnetic flux passing the coil changes by its rotation thus induced emf is produced and induced current flows
Why does voltage lead current in an inductor?
From what I've read, an inductor is designed to store energy in the form of a magnetic flux. A simple inductor can be thought of as a coil of wires around a medium. The current causes the flux to go through each turn of the coil. Further examination and Faraday's law leads to this model. v= N * D(magnetic flux) Because the current inside the coil is what generates the flux, the voltage will change first, before the flowing electrons will get all the way through the inductor. The inductance constant L is the Number of turns in the wire times the ratio of the current i to the magnetic flux, which is usually a constant. L = N*flux/i Which leads to this relationship between voltage and current in an inductor: v = L* D(i) The D() function being a derivative. Because the derivative of the current will change before the current actually does, voltage leads current in an inductor.
