(I) A single square loop of wire 22.0 cm on a side is placed with its face parallel to the magnetic field as in Fig. 20-34b. When 5.70 A flows in the coil, the torque on it is 0.325 m • N. What is the magnetic field strength?
(II) The force on a wire is a maximum of 8.50 X 10-2 N when placed between the pole faces of a magnet. The current flows horizontally to the right and the magnetic field is vertical. The wire is observed to “jump” toward the observer when the current is turned on. (a) What type ofmagnetic pole is the top pole face? (b) If the pole faces have a diameter of 10.0 cm, estimate the current in the wire if the field is 0.220 T. (c) If the wire is tipped so that it makes an angle of 10.0° with the horizontal, what force will it now feel? [Hint: What length of wire will now be in thefield?]
