The figure below shows a planar rectangular current loop (parallel to the plane of the page) immersed in a uniform 0.500 T magnetic field which is directed upward and parallel to the plane of the page, as shown in the Figure. The rectangular metal loop has a width of 15.0 cm and a height of 20.0 cm; the loop carries a counterclockwise current of 3.00 A, as shown in the Figure. I 20.0 cm B uniform and parallel to the plane of the page H I 15.0 cm 31. The magnetic force on the top side of the current loop has a magnitude of A. ZERO. B. 22.5 N. C. 0.300 N. D. 0.225 N. E. 30.0 N 32. The direction of the magnetic dipole moment of the current loop is A. out of the page at right angles. B. into the page at right angles. C. straight down and parallel to the page. D. to the left, horizontal, and parallel to the page. E to the right, horizontal, and parallel to the page. 33. How will this current loop begin to turn if released from rest in the orientation shown in the figure above? Assume that the downward pull of gravity is negligible. A. Top side moves out of the page and bottom side moves into page. B. Left side moves into the page and right side moves out of the page. C. Top side moves into the page and bottom side moves out of the page. D. Right side moves into the page and left side moves out of the page. E. The current loop will not begin to turn.
A uniform magnetic field exists in a region of space. The magnetic field is directed INTO the page and perpendicular to the page, as shown in the Figure below. A circular conducting wire loop is placed in the magnetic field; the loop is oriented parallel to the plane of the page, as shown in the Figure. ® 8 100 34. If the strength of the magnetic field is decreased, in which "direction will the induced current in the wire loop go? A. counterclockwise. B. clockwise. C. No current is induced in the wire loop. A bar magnet's south pole is moved rapidly away from a coil of conducting wire which is connected to a galvanometer. The bar magnet is moved along the central axis of the coil, as shown in the figure. South pole of bar magnet moved rapidly away from the coil. a 35. The current induced in the coil will be A up in the front side of the coil, deflecting the galvanometer needle to the left. B. down in the front side of the coil, deflecting the galvanometer needle to the right. C. No current will be induced in the coil.
