# A solid current carrying conductor of radius R is having current per unit area (J) as $J=\frac{\alpha r}{R}$ where α is constant and r is distance from axis. Find magnetic field at distance x from axis of wire. Assume x > R. (1) $\frac{{µ}_{0}\alpha {R}^{2}}{3x}$                            (2) $\frac{{µ}_{0}\alpha {R}^{2}}{2x}$ (3) $\frac{{µ}_{0}\alpha {R}^{2}}{x}$                            (4) Zero
