a) A circular coil of radius R is carrying a constant current I. Find an expression for magnetic field at point P, which is at a distance x on its axial line.
b) Why is Hall voltage much more measurable in semiconductors than metals? Explain.
c) Draw magnetic field lines around the two parallel current carrying conductors in which currents are in opposite direction.
d) Two long parallel conductors are placed 0.1 m apart and carry currents of 3 A and 2 A, respectively in the same direction. Calculate the force per unit length experienced by each conductor due to the other. (\( \mu_0 = 4\pi \times 10^{-7}\text{Hm}^{-1} \))
