The emf of a coil rotating in a magnetic field is zero at t=0, and the coil rotates at an angular velocity of 20 rad/s. At what time (in seconds) is the emf first at its most negative?
Your answer should be a number with three decimal places, do not include the unit.

A circular coil (800 turns, radius = 0.040 m) is rotating in a uniform magnetic field. At t = 0 s, the normal to the coil is perpendicular to the magnetic field. At t = 0.028 s, the normal makes an angle of 45o with the field because the coil has made one-eighth of a revolution. An average emf of magnitude 0.094 V is induced in the coil. Find the magnitude of the magnetic field at the location of the...
