PHYS 202 Midterm: PHYS 202 TAMU s10 Exam 2 Solutions
Document Summary
No work needs to be shown and no partial credit will be given. (6 pts) 1. A rectangular wire loop with area 0. 060 m2 and resistance 0. 80 1 is at rest in a uniform magnetic field. The loop has a constant clockwise current i = 2. 0 a. The magnetic field has a constant magnitude and direction. B = 0. 50 t and the magnetic field is directed into the page, as shown in the sketch. For the axis shown in the sketch, the magnitude of the torque on the current loop is. _41 x (a) 0. 060 n m (b) 0. 048 n m (d) 1. 20 nm (e) 1. 60 n m (f) none of these answers. A circular loop of wire is near the wire and moving away from it with constant speed v. the current induced in the loop of wire is q c2ercckwise (c) zero. A long straight wire carries constant current i in the direction shown in the sketch.
