What does flux depend on?

What does flux depend on?

Flux is the amount of “something” (electric field, bananas, whatever you want) passing through a surface. The total flux depends on strength of the field, the size of the surface it passes through, and their orientation.

What affects the flux?

The factors affecting flux are shown to be film heat transfer, membrane ‘thermal’ permeability, the partial pressure of air within the pores and the presence of solute in the feed. Solute effects mainly influence vapour pressure and film transfer coefficients.

Why is the flux the same?

The net flux is determined by the strength of the source, not by the surface through which the light passes. As has already been pointed out the net flux across any closed surface is the same and only depends on the charge enclosed.

Does flux depend on number of turns?

Faraday’s law states that the EMF induced by a change in magnetic flux depends on the change in flux Δ, time Δt, and number of turns of coils.

What is 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.

What is the flux not depend on?

Gauss’s law of electricity, which is included within the fundamental laws of electromagnetism, states that the electric flux through a closed surface with electric charge inside, just depends on the net charge enclosed in the surface and does not depend the shape or size of the surface.

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.

Does increasing current increase flux?

The induced current in a loop of wire will be in a direction that opposes the change in flux through the loop. In other words, if the flux through the loop is being increased, then the induced current will create its own flux that will try to cancel out the increase in flux.

Can flux be negative?

The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero. If a net charge is contained inside a closed surface, the total flux through the surface is proportional to the enclosed charge, positive if it is positive, negative if it is negative.

Is flux the same as intensity?

The conceptual difference is that the flux is total brightness of an object, while intensity defines its brightness at a given position (for example, the projected center of a galaxy).

Why does flux not depend on shape?

As per the Guess theorem in electrostatics, electric flux does not depend on the shape or size of the surface. The electric flux depends only on the charge enclosed by the surface.

How is the magnetic flux related to the surface normal?

Varying Magnetic Field: Each point on a surface is associated with a direction, called the surface normal; the magnetic flux through a point is then the component of the magnetic field along this normal direction.

What’s the difference between induction and magnetic flux?

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. As seen in previous Atoms, any change in magnetic flux induces an electromotive force (EMF) opposing that change—a process known as induction. Motion is one of the major causes of induction.

How is an EMF used in an induction experiment?

Induction Experiments(Faraday / Henry) – If the magnetic flux through a circuit changes, an emf and a current are induced. – A time-varying magnetic field can act as source of electric field. – A time-varying electric field can act as source of magnetic field.
