Axis of a solid cylinder of infinite length and radius
\( \mathrm{P} \)
\( R \) lies along \( y \)-axis it carries a uniformly distributed current ' \( i \) ' along \( +y \) direction. Magnetic field at a point \( \left(\frac{R}{2}, y, \frac{R}{2}\right) \) is:
(1) \( \frac{\mu_{0} I}{4 \pi R}(\hat{i}-\hat{k}) \)
(2) \( \frac{\mu_{0} I}{2 \pi R}(\hat{j}-\hat{k}) \)
(3) \( \frac{\mu_{0} I}{4 \pi R} \hat{j} \)
(4). \( \frac{\mu_{0} I}{4 \pi R}(\hat{i}+\hat{k}) \)
