How to Calculate and Solve for Magnetic Field | Magnetic Field

The image above represents magnetic field. To calculate magnetic field, four essential parameters are needed and these parameters are Magnetic Permeability of Vacuum (μ_o), Strength of Magnetic Pole (m), Relative Magnetic Permeability (μ_R) and Seperating Distance (r).

The formula for calculating magentic field:

B = ^μ_om / _4πμRr²

Where:

B = Magnetic Field
μ_o = Magnetic Permeability of Vacuum
m = Strength of Magnetic Pole
μ_R = Relative Magnetic Permeability
r = Separating Distance

Let’s solve an example;
Find the magnetic field when the magnetic permeability of vaccum is 1.2566371E-6, strength of magnetic pole is 11, relative magnetic permeability is 9 and the seperating distance is 12.

This implies that;

μ_o = Magnetic Permeability of Vacuum = 1.2566371E-6
m = Strength of Magnetic Pole = 11
μ_R = Relative Magnetic Permeability = 9
r = Separating Distance = 12

B = ^μ_om / _4πμRr²
B = ^{(0.0000012566371)(11)} / _4π(9)(12)²
That is, B = ^0.00001382 / _4π(9)(144)
B = ^0.00001382 / _(16286.0163)
B = 8.487e-10

Therefore, the magnetic field is 8.487e-10.
