be briefly considered. This enables us to write all dimensions as L 
or its powers.

It will be observed that magnetic quantity q;; now becomes L?, 
and has the dimensions of electrical quantity, (e).

Both are L?. 
And this is the same as the dimensions of force and also of gravitational 
permeability. Now the only way we recognize magnetism or elec- 
tricity is by the force it exerts on charged bodies. It is, therefore, 
extremely interesting that all three are nothing but force, L?. Mag- 
netic induction and magnetic pole are also L’.
