How Does Dimensional Analysis Prove mH Equals Force in Magnetism?

AI Thread Summary
In magnetism, the equation mH = F establishes that the product of pole strength (m) and magnetic field intensity (H) equals force (F). The dimensional analysis shows that the dimensions of mH correspond to [MLT^-2], which is the dimension of force. This relationship can be derived from the fundamental equation F = ma, where mass (M) is multiplied by acceleration (LT^-2). The discussion emphasizes that this is primarily an exercise in dimensional analysis rather than a deep exploration of magnetism itself. Understanding this relationship clarifies how magnetism relates to fundamental physical principles.

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


F = [ MLT^{}-2]

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

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 excercise in magnetism as in rather basic dimensional analysis.

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
