Statement of a problem № 42034


A steel guitar string vibrates (Figure 31.6). The component of magnetic field perpendicular to the area of a pickup coil nearby is given by B = 50.0 mT 2 (3.20 mT) sin (2, 523 t/s) The circular pickup coil has 30 turns and radius 2.70 mm. Find the emf induced in the coil as a function of time.
