Chapter 27.1, Problem 27.1TYU
Suppose you cut off the part of the compass needle shown in Fig. 27.5a that is painted gray. You discard this part, drill a hole in the remaining red part, and place the red part on the pivot at the center of the compass. Will the red part still swing when a current is applied as in Fig. 27.5b?

The door to my office is 0.88 m wide and 2.39 m high, with an aluminum frame around the very edge.With the door open, as shown, it faces to the north. (That is, if I stand with my back to the door, I am looking north.) Since the earth's magnetic field equals 5.0 x 10-5 T and points to the north, what flux, if any, is caught by the open door? Express your answer to two significant figures in exponential notation.
What maximum value of flux can pass through the square loop of wire 10 cm on a side and is in a 1.25 T magnetic field?
What will be the total magnetic flux through a coil of wire when the surrounding magnetic field is 0.5 T, and its cross-sectional area is 0.25 m2 ? The coil is perpendicular to the field. (5 points) Show solution.
