How Does Dimensional Analysis Prove mH Equals Force in Magnetism?

Click For Summary
SUMMARY

The discussion centers on the relationship between magnetic pole strength (m), magnetic field intensity (H), and force (F) in the context of dimensional analysis, establishing that mH equals force. Specifically, it confirms that the dimensions of mH are equivalent to [MLT^-2], which is the dimensional representation of force. The proof is derived from the equation F = mH, where F represents force as mass times acceleration, reinforcing the foundational principles of dimensional analysis in physics.

In magnetism ,
mH = F, where m = pole strength ; H= magnetic field intensity ; and
F = Force.


F = [ MLT[tex]^{}-2[/tex]]

Proof that dimension of mH = [MLT[tex]^{}-2[/tex]]

Can you figure out the dimensions from the units of m and H? What are you not understanding? You didn't really ask a question.
 
If you wish to proove from F=mH that mH has dimensions of MTL-2, just consider that mH is equal to a force, which is equal to mass times acceleration: M*LT-2.

This is not as much an exercise in magnetism as in rather basic dimensional analysis.
