1.	A magnetic needle is kept in a non uniform magnetic field . It experiencesA. a force and a torqueB. a force but not a torqueC. a torque but not a forceD. nither a force nor a torque
Answer» Correct Answer - B If the plane of magnetic field and the coil are hoizontal and vertical respectively then `theta=0`. Thus, torque on the coil is given by , `tau_(n)=n IAB cos theta= n IAB cos 0 = n IAB`.
