Question:
Using the formulae
$\overrightarrow{\mathrm{F}}=\mathrm{qv} \times \overrightarrow{\mathrm{B}}$ and $\mathrm{B}=\frac{\mu_{0} \mathrm{i}}{2 \pi \mathrm{r}}$
show that the $\mathrm{SI}$ units of the magnetic field $B$ and the permeability constant $\mu_{0}$ may be written as $N / A-m$ and $N / A^{2}$ respectively.
