Idea: build the unit up from relations you know.
T m² is field times area, which is magnetic flux: 1 T m²=1 Wb.
So T m² A⁻¹=Wb A⁻¹, flux per unit current.
From Φ=LI, inductance is L=Φ/I, measured in Wb A⁻¹=H.
So T m² A⁻¹ is the unit of inductance.
Reading this solution needs no sign-in. You only sign in to practise against the clock and keep your progress.
Practise this with a timer
