How do you calculate flux density in an air gap?

How to Calculate Flux Density in an Air Gap?

  1. B = μ x H ….. ( Equation 1)
  2. H = Fm / l ….. ( Equation 2)
  3. B = μ x (Fm/l) Solving the above equation for magnetomotive force, we get.
  4. Fm = Bl / μ …….. ( Equation 3)
  5. μair = 4π x 10-7 H/m.
  6. Fm = BL / (4π x 10-7)

How do you calculate flux density?

Flux Density Example

  1. First, determine the total flux. Calculate the total flux generated from the magnetic field.
  2. Next, determine the total area. Measure the total area the flux is acting on.
  3. Finally, calculate the flux density. Divide the flux by the area to find the flux density.

How is flux density measured?

The magnetic flux density of a magnet is also called “B field” or “magnetic induction”. It is measured in tesla (SI unit) or gauss (10 000 gauss = 1 tesla). The effecting force is proportional to the strength of the B field.

What is the formula for magnetic flux density?

Magnetic Flux Density Formula. Its letter symbol is B. The relationship between total flux and flux density is given by the following equation: B = φ A B = φ A. Where. B=flux density in Tesla. φ=total magnetic flux in weber. A= Cross-sectional area in square meter.

How do you find the flux of a magnetic field line?

If the field lines intersect the area at a glancing angle, that is, when the angle between the magnetic field vector and the area vector is nearly equal to 90ᵒ, then the resulting flux is very low. When the angle is equal to 0ᵒ, the resulting flux is maximum. ϕB = B.A= BAcos Θ ϕ B = B.

What is the SI unit of magnetic flux?

The SI unit of magnetic flux is Weber (Wb) or tesla meter squared (Tm 2) named after German physicist Wilhelm Weber. Magnetic flux can be measured with a magnetometer.

Is magnetic flux a scalar or vector quantity?

It is clear from the equation given above that the magnetic flux is a scalar quantity. Its SI unit is given as Weber (Wb) or tesla meter squared (Tm 2 ). The SI unit of magnetic flux is Weber (Wb) or tesla meter squared (Tm 2) named after German physicist Wilhelm Weber.
