The magnetic field vector B is defined by the force it would apply to a charge moving in it. B = F/qv, so the units are (N *s) / (C *m), which we call a Tesla, or T. This is also called flux density. Flux is then given by B*A, so it is in T*m^2, which we also call a Weber.

## How is magnetic flux density measured?

To calculate the strength of a magnetic force on a wire you must find the magnetic flux density . This is measured in a unit called tesla. … The equation for calculating the force on a wire is Force (N) = magnetic flux density (T) × current (A) × length (m) or, in short F = B I L.

## How do you calculate magnetic flux?

ΦB=B⋅A=BAcosθ Φ B = B ⋅ A = BA cos , where B is the magnitude of the magnetic field (having the unit of Tesla, T), A is the area of the surface, and θ is the angle between the magnetic field lines and the normal (perpendicular) to A.

## Is magnetic flux density?

Magnetic flux density is defined as the amount of magnetic flux in an area taken perpendicular to the magnetic flux’s direction. An example of magnetic flux density is a measurement taken in teslas. … A vector quantity measuring the strength and direction of the magnetic field around a magnet or an electric current.

## What is magnetic flux density?

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 unit of magnetic flux density?

tesla (T)

## What is SI unit of flux?

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 flux with example?

Flux is a chemical purifying agent, flowing agent or cleaning agent. … Some examples of flux include: Ammonium chloride. Zinc chloride. Hydrochloric acid.22 мая 2014 г.

## When magnetic flux is maximum?

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.

## What is flux density formula?

Flux density is simply the total flux divided by the cross sectional area of the part through which it flows – B = Φ / Ae teslas. Thus 1 weber per square metre = 1 tesla. Flux density is related to field strength via the permeability. B = μ × H.

## What is motional EMF?

About Transcript. An emf induced by motion relative to a magnetic field is called a motional emf. This is represented by the equation emf = LvB, where L is length of the object moving at speed v relative to the strength of the magnetic field B.

## What is magnetic flux symbol?

Magnetic flux is commonly denoted using Greek letter Phi or Phi suffix B. Magnetic flux symbol: Φ or ΦB.

## What is maximum flux density?

The maximum value of the magnetic flux density is 1.1T when 2200 volts, 50Hz is applied to the transformer primary winding.

## What is the SI unit of magnetic field?

tesla
