Magnetic flux density is a vector field which we identify using the symbol B and which has SI units of tesla (T).

## What is the magnetic flux density of a solenoid?

Therefore, the magnetic flux density at a point on the axis of the long solenoid is 0.0126 T. Additional information: The magnetic field along the axis of an ideal solenoid is uniform while the magnetic field at some distance away from the axis of solenoid becomes zero.

**What is the formula of flux in a solenoid?**

Magnetic field in a solenoid formula is given as B = μ0 nl.

In the formula, B represents the magnetic flux density, μ0 is the magnetic constant whose value is 4π x 10-⁷ Hm or 12.57 x 10−⁷ Hm, N represents the number of turns, I is the current flowing through the solenoid.

**What is the symbol of magnetic flux?**

Φ

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

### What is formula of magnetic 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. It is measured in Webers per square meter equivalent to Teslas [T].

### Why is magnetic field symbol B?

In 1873, he wrote a book named “A treatise on Electricity and Magnetism”. In this book, he randomly assigned alphabets to vectors. He assigned A for vector potential, B for the magnetic field, E as electric field, and so on.

**What is magnetic flux density formula?**

Flux Density (B) is related to Magnetic Field (H) by B=μH. It is measured in Webers per square meter equivalent to Teslas [T]. The total number of magnetic field lines passing through a given area normally is called magnetic flux.

**What is the unit of N in solenoid?**

n refers to the number of turns per unit length. As we know the solenoid is in form of a circular ring. So, the length will become the circumference of the circle.

#### What is magnetic flux write its SI unit?

Updated On: 27-06-2022. UPLOAD PHOTO AND GET THE ANSWER NOW! Solution : Magnetic flux:Magnetic flux through any surface in magnetic field `vecB` is equal to the total number of magnetic lines of force crossing the surface `A`. <br> `therefore phi=BA cos theta`. Its `SI` unit is weber.It is scalar quantity.

#### What is the symbol of electric flux density?

symbol D

Electric flux density, assigned the symbol D, is an alternative to electric field intensity (E) as a way to quantify an electric field.

**What is B and H in magnetic field?**

The definition of H is H = B/μ − M, where B is the magnetic flux density, a measure of the actual magnetic field within a material considered as a concentration of magnetic field lines, or flux, per unit cross-sectional area; μ is the magnetic permeability; and M is the magnetization.

**What is N and N in solenoid?**

N = number of turns in the solenoid. I = current in the coil.

## How do you calculate the magnetic flux density of a coil?

AS per Biot-savart’s law, the magnetic field at point C due to current element AB. Therefore, An expression for magnetic flux density B at the center of a circular coil of radius R, having N turns and carrying a current $I$ is given by $B = \dfrac{{{\mu _o}NI}}{{2R}}$.

## What is magnetic flux density and its SI unit?

The SI derived unit of magnetic flux density is the tesla, which is defined as a volt second per square meter.

**What is the significance of density of electric flux ∆ ϕ ∆ s?**

Electric flux density is the electric flux passing through a unit area perpendicular to the direction of the flux. Electric flux density is a measure of the strength of an electric field generated by a free electric charge. Was this answer helpful?

**What are B and H and m?**

### What is H and B?

The difference between B and H is that B is used for representing the magnetic flux density while H is used for representing the magnetic field intensity. Stay tuned with BYJU’S to learn more about other concepts such as the difference between electric field and magnetic field.

### What is the unit of magnetic flux density?

The SI unit of magnetic flux is the Weber (Wb). A flux density of one Wb/m2 (one Weber per square metre) is one Tesla (T).

**What is MMF formula?**

Magnetomotive force (mmf), Fm = NI ampere-turns (At), where N = number of conductors (or turns) and I = current in amperes.

**What is the dimensional formula of magnetic flux density?**

The dimensional formula of magnetic flux density is [MT−2L0A−1]

#### What is H&M stand for?

Hennes & Mauritz

1968. The name is changed to Hennes & Mauritz when Erling Persson buys the hunting and fishing store Mauritz Widforss in Stockholm, including a stock of men’s clothing. This is the start of sales of men’s and children’s clothing. 1974. H&M is listed on the Stockholm Stock Exchange.

#### How do you read H&M?

**What is the formula of magnetic field?**

F=ILBsinθ where θ is the angle between the wire and the magnetic field. The force is perpendicular to the field and the current. The equivalent formula for the force on a moving charged particle of charge q and velocity v is F, equals, q, v, B, sine, theta,F=qvBsinθ, with the force perpendicular to field and velocity.

**What is H and B in pencils?**

The degree of hardness of a pencil is printed on the pencil.

B stands for “black”. These pencils are soft. H stands for “hard”. HB stands for “hard black”, which means “medium hard”.

## What is magnetic flux density equation?

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.
