$\frac{{{\mu _0}ni}}{4}(\sqrt 3 + 1)$

Vedclass · Answer

(A) The magnetic field on the axis of a finite solenoid at a point $P$ is given by the formula:$B = \frac{{{\mu _0}ni}}{2}(\sin 	heta_1 + \sin 	heta_2)$where $	heta_1$ and $	heta_2$ are the angles subtended by the ends of the solenoid at point $P$.From the figure,$	heta_1 = 60^\circ$ and $	heta_2 = 30^\circ$.Substituting these values into the formula:$B = \frac{{{\mu _0}ni}}{2}(\sin 60^\circ + \sin 30^\circ)$$B = \frac{{{\mu _0}ni}}{2}(\frac{\sqrt{3}}{2} + \frac{1}{2})$$B = \frac{{{\mu _0}ni}}{4}(\sqrt{3} + 1)$
