A wire of length \(5\,mm\) carries a current of \(5A\) along the X-axis. Find the magnetic field at a point on the Y-axis at a distance \(1m\).
Show Hint
For a short current element,
\[
dB=\frac{\mu_0}{4\pi}\frac{Idl\sin\theta}{r^2}
\]
which is the differential form of Biot-Savart law.

- Moving charges and magnetism
- A particle of charge \( q \) is moving with a velocity \( \vec{v} \) at a distance \( d \) from a long straight wire carrying a current \( I \) as shown in the figure. At this instant, it is subjected to a uniform electric field \( \vec{E} \) such that the particle keeps moving undeviated. In terms of unit vectors \( \hat{i}, \hat{j}, \) and \( \hat{k} \), find:
the magnetic field \( \vec{B} \),
the magnetic force \( \vec{F}_m \), and
the electric field \( \vec{E} \) acting on the charge.
