In a physics laboratory experiment, a coil with 160turns enclosing an area of 13.4 cm² is rotated duringthe time interval 4.20×10-2 s from a position in whichits plane is perpendicular to Earth's magnetic field toone in which its plane is parallel to the field. Themagnitude of Earth's magnetic field at the lab locationis 6.90x10-5 T. What is the magnitude of the average EMF induced in the coil?Express your answer numerically in Volts.View Available Hint(s)?Average Induced EMF =V

According to Faraday's law of electromagnetic induction The induced emf in the coil is given by Where = Magnetic flux, t = timeThe number of turns in the coil is N = 160 The area of the coil is A = 13.4 cm2 = 0.00134 m2 time interval t = 4.20 × 10- 2 s Earth magnetic field B = 6.90 × 10- 5 T Initially plane of the coil is perpendicular to the magnetic field. Thus magnetic flux through the coil is i = NBA Cos(0o) Where 0o is the angle between the magnetic field and area vector of the coil. Thus i = 160 × 6.90 × 10- 5 × 0.00134 × 1 i = 1.47936 × 10- 5 T.m2 At the final position, the plane of the coil is parallel to the magnetic field. Then magnetic flux through the coil is f =NBA Cos(90o) f = 0 T.m2 Because Cos(90o) = 0 The change in magnetic flux through the coil is Using Faraday's law of electromagnetic induction The induced emf in the coil is given by Average induced emf =
