answer both for good rating

A square coil of wire of side 2.50 cm is placed in a uniform magnetic field of magnitude 1.50 T directed into the page as in the figure shown below. The coil has 35.0 turns and a resistance of 0.780 2. If the coil is rotated through an angle of 90.0° about the horizontal axis shown in 0.335 s, find the following. Rotation axis X X X X X X X X (a) the magnitude of the average emf induced in the coil during this rotation mV (b) the average current induced in the coil during this rotation mA Need Help?

MY NOTES ASK YOUR TEACHER A flat coil enclosing an area of 0.30 m2 is rotating at 62 rev/s, with its axis of rotation perpendicular to a 0.21 T magnetic field. (a) If there are 1030 turns on the coil, what is the maximum voltage induced in the coil? v (b) When the maximum induced voltage occurs, what is the orientation of the coil with respect to the magnetic field? The plane of the coil is at a 41° angle to the magnetic field. The plane of the coil is at a 62° angle to the magnetic field. The plane of the coil is parallel to the magnetic field. The plane of the coil is perpendicular to the magnetic field. Need Help? Read It
