1. (Table A & B) A 1 turn loop is pulled out of a 2.0 T field at a velocity of 1.5 m/s to the right. A. Compute the induced emf in the loop and find the direction of the induced current. 75 points 15 points 15 points 10 points 15 points ï ¿ ¼B. A 25 turn loop extends 0.1 m into a uniform field that is decreasing at -3 T/s. Compute the induced emf in the loop and find the direction of the induced current. 2. (Tables C & D) A rod with a mass of 0.720 kg and a radius of 6.00 cm rests on two parallel rails (see the figure below) that are d = 12.0 cm apart and L=45.0 cm long. The rod carries a current of I = 48.0 A in the direction shown and slides along the rail. If it starts from rest, what is the speed of the rod as it leaves the rails if a uniform magnetic of 0.240 T is directed perpendicular to the rod and the rails? 3. (Tables E & F) A proton enters a region with a uniform magnetic field after being accelerated across a potential of 5000 Volts. The proton moves in a circle due to the magnetic force. If the ï ¿ ¼Ã¯ ¿ ¼ strength of the magnetic field is 2.5 T, what is the period of the proton's ci...
