A door is 0.85 m wide and 2.25 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.
Homework Answers
Area of door (A) = 2.25 X 0.85 = 1.9125 m^2
Magnetic field (B) = 5.0 X 10^-5 T
Flux = B X A = 5.0 X 10^-5 X 1.9125 = 9.6 X 10^-5 weber.

Josh's office door is 0.82 m wide, 6.0 cm thick, and 2.10 m high. The door has a mass m = 15.0 kg and pivots on frictionless hinges. A door closer is attached to the door and the top of the door frame. When the door is open and at rest, the door closer exerts a torque Γ = 4.50 N m. What is the smallest force that you need to apply to the door to hold it open? Enter your...

1. An electron moves in a circular path in the magnetic field of an electromagnet. The plune of the electron's Sicular path is parallel to the smooth vole faces of the electromagnet. In the region where the electron is moving the magnetic field is uniform and has magnitude 0,50 T. The electron moves with a speed of 1.5 x 10 m/s. a. If someone could observe the electron from the north pole of the electromagnet, would the electron inove clockwise...
