Multiple-choice questions may continue on the next column or page – find all choices before answering. The due time is Central time. Covers 29.1-29.3 Induced EMF in a Coil 31:01, calculus, numeric, > 1 min, normal. 001 A 30 turns circular coil with a radius 4 cm and a resistance 1 Ω is placed in a magnetic field directed perpendicular to the plane of the coil. The magnitude of the magnetic field varies in time according to the expression B = a 1 t + a 2 t 2 , where a 1 = 0 . 01 T / s, a 2 = 0 . 04 T / s 2 are constants, time t is in seconds and field B is in Tesla. Calculate the magnitude of the induced E in the coil at t = 5 s. Answer in units of V. Applied Force on a Bar 02 31:02, trigonometry, numeric, > 1 min, wording-variable. 002 In the arrangement shown in the figure, the resistor is 5 Ω and a 4 T magnetic field is directed out of the paper. The separation between the rails is 3 m . Neglect the mass of the bar. An applied force moves the bar to the left at a constant speed of 2 m / s . Assume the bar and rails have negligible resistance and friction. m
