Calculate magnetic flux density, flux, area, attractive force, core Bmax, or solenoid current from voltage, turns, and permeability.
Flux Density Formula
For a uniform magnetic field normal to a surface, the following formula gives flux density. With a nonuniform field, it gives the average normal component.
- Where FD is the flux density
- Φ is the total flux
- A is the total area
To calculate average normal flux density, divide magnetic flux in webers by normal area in square metres to obtain teslas.
Flux Density Definition
Magnetic flux density is the magnetic field B. The ratio Φ/A gives its average normal component over the specified surface.
Flux Density Example
How to calculate flux density?
- First, determine the total flux.
Calculate the total flux generated from the magnetic field.
- Next, determine the total area.
Measure the total area the flux is acting on.
- Finally, calculate the flux density.
Divide the flux by the area to find the flux density.
FAQ
Flux density is the total flux per unit area that is being generated by a magnetic field.
