A circular loop of area 0.04m2 is rotating in a uniform magnetic field of 0.4T. The loop rotates about its diameter which is perpendicular to the magnetic field. The magnetic flux through the loop when the plane of the coil is normal to the field and when it is making 30∘ with the field are respectively (in Wb)
