1.	Under which of these conditions, the torque acting on the current carrying loop is minimum?(a) θ = 0^o(b) θ = 90^o(c) θ = 270^o(d) θ = 450^oThe question was asked by my college director while I was bunking the class.The above asked question is from Torque on Current Loop & Magnetic Dipole topic in chapter Moving Charges and Magnetism of Physics – Class 12
Answer» Right option is (a) θ = 0^o For explanation I WOULD say: When θ = 0^o ➔ τ = 0. The torque is minimum when the PLANE of the loop is perpendicular to the MAGNETIC FIELD, so the angle θ should be 0^o.
