Here are the solutions to the questions:
5. (a) A long straight wire 2mm is diameter is carrying a current of 5A, calculate the magnetic induction B, at distances of 0.1m, 0.2m and 0.4m (Take $\mu_0 = 4\pi \times 10^{-7}$ Wb/A-m.
The magnetic field $B$ at a distance $r$ from a long straight current-carrying wire is given by:
$$B = \frac{\mu_0 I}{2\pi r}$$
Given: Current $I = 5 \, \text{A}$, $\mu_0 = 4\pi \times 10^{-7} \, \text
