Hmagnetic field intensity (A/m)
Description
What is this formula?
This formula calculates the magnetic flux density inside a material subjected to a magnetic field. Magnetic permeability determines how easily a material supports magnetic field formation.
When to use it
Use this equation when analyzing magnetic materials, transformers, inductors, electromagnets, and electromagnetic field propagation in matter.
Example
A magnetic material has a permeability of 2.5×10^-3 H/m and is subjected to a magnetic field intensity of 1800 A/m. Calculate the magnetic flux density.
Data:
mu = 2.5×10^-3 H/m
H = 1800 A/m
Formula:
B = mu*H
Substitution:
B = 2.5×10^-3*1800
Result:
B = 4.5 T
