Dimensional formula of intensity of magnetisation

Intensity of magnetisation
[L−1 A]
Written in full: [M⁰ L⁻¹ T⁰ A¹ K⁰]

How to derive it

Intensity of magnetisation = Magnetic moment ÷ Volume

Put in the dimensions of each part: [AL²] ÷ [L³] = [L⁻¹ A].

SI unit

The SI unit of intensity of magnetisation is A/m.

Same dimensions as intensity of magnetisation

These quantities have exactly the same dimensions, a favourite trick in JEE and NEET "which pair has the same dimensions" questions:
