Using the formulae (`(vecF)=(vec qv)xx (vec B) and B= (mu_0)i/(2pi r )`,find the SI units of the magnetic field B and the permeability constant

Explanation

To find the SI units of the magnetic field \( B \) and the permeability constant \( \mu_0 \), we will follow the steps outlined in the video transcript.

### Step 1: Find the SI unit of the magnetic field \( B \)

We start with the formula for the magnetic force:
\[ \vec{F} = \vec{q} (\vec{v} \times \vec{B}) \]
