You are working in your dream job: an assistant for the special effects department of a movie studio. You have just been given this assignment: the star of a horror movie is walking down a spooky hallway when suddenly, due to some unknown and strange supernatural forces, all the pictures hanging on the wall start rotating about their pper edges until they are sticking straight out from the wall! To set up this effect, you attach the pictures to the wall with hinges along their upper end and wrap 20 turns of wire around the outside frame of the picture, as shown in figure (a). 1-71 Wall Hinge Turns of wire Picture frame a b u set up a uniform magnetic field in the hallway that is directed upward and oriented at an angle of y5.00° to the vertical, with its horizontal component directed perpendicularly into the wall. When you send a current of I= 11.4 A through the wire around each picture, the frame swings up perpendicular to the wall as shown in figure b). Consider a particular picture of width w39.0 cm, height = 50.0 cm, and mass m 0.950 kg. (a) Your supervisor asks you to determine the magnetic field magnitude (in T) that is necessary for this picture to rotate so that its face is parallel to the floor and perpendicular to the wall, as in figure (b). (b) She also asks about any dangers associated with this magnetic field. (Select all that apply) Such a strong magnetic field may cause metal objects to become projectiles. There is no danger associated with this magnetic field. Such a strong magnetic field may cause human tissues to become dangerously magnetized.

To set up this effect, you attach the pictures to the wall with hinges along their upper end and wrap 20 turns of wire around the outside frame of the picture, as shown in figure (a). 171 Wall Hinge. Turns of wire Picture. frame b You set up a uniform magnetic field in the hallway that i directed upward and oriented at an angle of y = 5.00° to the vertical, with its horizontal component directed perpendicularly into the wall. When you send a current of I = 11.4 A through the wire around each picture, the frame swings up perpendicular to the wall as shown in figure (b). Consider a particular picture of width w = 39.0 cm, height h = 50.0 cm, and mass m = 0.950 kg.
