Aflat coil of wire has an area a, n turns, and a resistance r. it is situated in a magnetic field, such that the normal to the coil is parallel to the magnetic field. the coil is then rotated through an angle of 90˚, so that the normal becomes perpendicular to the magnetic field. the coil has an area of 1.5 × 10-3 m2, 50 turns, and a resistance of 180 ω. during the time while it is rotating, a charge of 9.3 × 10-5 c flows in the coil. what is the magnitude of the magnetic field?
