- Problem3 Your textbook calls the electric generator "probably the most important technological application of induction." Let's consider an example of such a generator, consisting of a single round loop of wire of R 100 Ω. The loop is rotated at a frequency f of 60 turns per second (and thus at 60x 2π radians per second). As shown in the figure below, the rotation axis of the loop is through its diameter and perpendicular to the page, and the loop rotates clockwise. We place the loop in a uniform magnetic field of strength B 0.50 T that points to the right. Note that the loop is arranged so that its rotation axis is perpendicular to the field. The angle θ measures the angle between the field and the normal onto the plane of the loop. An oscillating current with an amplitude of lo 1.5 A is induced Pivot Circular loop (a) Assuming we let t 0 correspond to θ 0° (i.e., the loop is vertical), show that the flux through the loop as a function of time is given by where r is the (unknown)…arrow_forwardFor a toroidal solenoid, suppose the number of turns is 175, the area is 4.56 cm 2, and the radius is 5.83 cm.
