Twelve > Magnetic Field due to a Current

Asked by Atith Adhikari · 2 years ago

Using the forumlae $\rm \vec{F} = q \vec{V} \times \vec{B}$ and $\rm B = \frac{\mu_{o} i}{2 \pi r}$, show that the SI units of the magnetic field B and the permeability constant $\rm \mu_{o}$ may be written as $\rm NmA^{-1}$ and $\rm NA^{-2}$ respectively.
