## What is the flux through the plane perpendicular to the field?

Answer: The magnetic flux through a unit area perpendicular to the field is Magnetic Flux Density. – It is defined as the amount of magnetic flux passing through per unit area of a section which is perpendicular to the direction of field.

## What is magnetic flux units?

The SI unit of magnetic flux is the weber (Wb in derived units volt–seconds) and the CGS unit is the maxwell. Magnetic flux is usually measured with a fluxmeter which contains measuring coils and electronics that evaluates the change of voltage in the measuring coils to calculate the measurement of magnetic flux.

## What is magnetic flux?

Magnetic flux is defined as the number of magnetic field lines passing through a given closed surface. It provides the measurement of the total magnetic field that passes through a given surface area.

## When the magnetic flux through a loop changes which is always true about the induced current?

When the magnetic flux through a loop changes which is always true about the induced current? It produces a magnetic field that opposes the existing magnetic field. It produces a magnetic field that is in the same direction as the existing magnetic field.

## Which describes the magnetic flux through a section of a loop?

Which describes the vector calculation of the magnetic flux through a section of a loop? It is the dot product of the magnetic field and the section’s area vector.

## What is the total magnetic flux through the solenoid?

The magnetic field in the middle of the solenoid is a uniform value of μ0nI. This field is producing a maximum magnetic flux through the coil as it is directed along the length of the solenoid. Therefore the magnetic flux through the coil is the product of the solenoid’s magnetic field times the area of the coil.

## What is flux through a solenoid?

solenoid: A coil of wire that acts as a magnet when an electric current flows through it. flux: The rate of transfer of energy (or another physical quantity) through a given surface specifically electric flux or magnetic flux.

## What happens to the flux as the north end of a magnet approaches the loop?

As the north pole of the magnet moves toward the loop the flux through the loop due to the field of the magnet increases because the strength of field lines directed from the front to the back of the loop is increasing.

## What is the magnetic flux through the coil?

The induced current produces a magnetic field which opposes the change in the magnetic flux. The magnitude of the induced emf can be calculated using Faraday’s law. The magnetic field inside the long coil is B = μ(N/ℓ)I. The flux through the coil is NBA = μ(N2/ℓ)IA.

## What is the maximum magnetic flux through the coil?

The magnetic flux through the plane of the coil has its maximum value when this plane is perpendicular to the magnetic field lines between the poles. As the coil turns and the plane of the coil becomes parallel to the field lines the flux becomes zero.

## Is the magnetic field inside the loop increasing in strength decreasing in strength or steady?

The field inducing current is into the plane of the page within the loop and has a changing strength. According to Lenz’s law the clockwise induced current produces a field out of the plane of the page that is opposing the change. Therefore the magnetic field inside the loop must be decreasing.

## Where does the magnetic field point on a wire with current?

Magnetic Field of Current

The direction of the magnetic field is perpendicular to the wire and is in the direction the fingers of your right hand would curl if you wrapped them around the wire with your thumb in the direction of the current.

## What is the magnetic flux through unit area perpendicular to the field?

The magnetic flux through a unit area perpendicular to the field is Magnetic Flux Density. – It is defined as the amount of magnetic flux passing through per unit area of a section which is perpendicular to the direction of field.

## What is the use of introducing the ideas of magnetic flux and magnetic flux density?

Magnetic flux density is equal to the flux divided by the area. It is represents by B and its unit is tesla. Magnetic flux : The number of magnetic field lines passing through a closed surface.

## When vector area is held perpendicular to the field lines then the magnitude of electric flux is?

zero

Along the other four sides the direction of the area vector is perpendicular to the direction of the electric field. Therefore the scalar product of the electric field with the area vector is zero giving zero flux.

## What is magnetic flux and 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. … The total number of magnetic field lines passing through a given area normally is called magnetic flux.

## What is magnetic flux linkage?

Flux linkage is the linking of the magnetic field with the conductors of a coil when the magnetic field passes through the loops of the coil expressed as a value. The flux linkage of a coil is simply an alternative term for total flux used for convenience in engineering applications.

## What is magnetic flux write its SI unit?

The total number of magnetic lines of force crossing any surface in the magnetic field is termed as magnetic flux. ∴ Φ = BA cos θ SI unit of magnetic flux is weber.

## What is magnetic flux in physics class 10?

Magnetic flux is defined as the number of magnetic field lines passing through a given closed surface. It provides the measurement of the total magnetic field that passes through a given surface area.

## What is flux and flux linkage?

Flux is the amount of the field through a particular surface. Flux linkage is the fraction of the outgoing flux from the source to the captured flux from the drain.

## What is magnetic flux density class 12?

Magnetic flux density is a vector quantity estimating the strength and direction of the magnetic field about a magnet or an electric current. Magnetic flux density is equivalent to magnetic field strength times the magnetic permeability in the field’s region.

## How does the magnetic flux change as the magnet rises?

When the magnet moves closer to the coil the flux rapidly increases until the magnet is inside the coil. As it passes through the coil the magnetic flux through the coil begins to decrease. Consequently the induced EMF is reversed.

## What happens when magnetic flux passing through a coil changes continuously?

Magnetic Flux is continually changing as coil rotates. Which of the three loops have a changing magnetic flux through it? Then an EMF (voltage) will be induced in the wire. This voltage will cause a current to flow (the induced current in the loop).

## What is the relation between magnetic flux and magnetic flux density?

The main difference between magnetic flux and magnetic flux density is that magnetic flux is a scalar quantity whereas magnetic flux density is a vector quantity. Magnetic flux is the scalar product of the magnetic flux density and the area vector.
