Problem Five: Qxis of ntation 010 20 R A rectangular metal coil consisting of six loops with sides a and 2a is rotating in a uniform magnetic field pointing out of the page. The angle between B and A is changing with time as the coil rotates. 16.) For the instant of time shown in the diagram, what is the direction of the Q induced emf? A.) CW around the coil B.) CCW around the coil C.) Normal In D.) Normal Out 17.) Suppose the rotation of the coil is driven by a motor so that the angle is given by the function , where a is a constant with appropriate units. Find an expression for the magnitude of the force induced on the top or bottom side of the coil if the entire coil has a total resistance R.

Consider if the motor driving the rotation of the coil is turned off and the coil is free to rotate with an average frequency of 90.0 Hz. The coil has sides 50.0 cm and 100.0 cm, with the total resistance of 400 n. The uniform magnetic field is 0.700 T. Find an expression for the current as a function of time. A.) 297muan] B.).
