When laws are to be found in magnetic field, the major unit is Coulomb. Two magnetic fields have squared distance between them, and when Coulomb force is inversely proportional to that, the ideal law of magnetic force comes to the fore.
As per experiments, it has been found that when magnetic force between 2 mediums is placed within dual magnetic poles, results are as follows:
- They are inversely proportional to square of that distance which prevails between them.
- If the surrounding medium is permeable, then it is inversely proportional to that permeable medium.
- It is also directly proportional to strength of poles.
A specific formula is usedfor getting the correct value of these units.
