Using the flux density calculator is straightforward. Input the required parameters into the designated fields, and with a click of a button, you’ll get the calculated flux density. The calculator automates complex mathematical operations, saving you time and effort.


The formula to calculate flux density (B) is given by:


  • B is the magnetic flux density (in teslas, T)
  • μ is the permeability of the material (in henries per meter, H/m)
  • I is the current flowing through the conductor (in amperes, A)
  • r is the radial distance from the center of the conductor (in meters, m)
  • π is the mathematical constant pi (approximately 3.14159)

Example Solve

Let’s consider an example where:

  • μ=4π×10−7 H/m
  • I=5 A
  • r=0.1 m

By substituting these values into the formula, we can calculate the flux density:
