HI everyone. I have tried all ideas to get the answer but with no help. The answer is 34 micro volts but i dont understand where it comes from:
Question:
A metal framed window is 1.3m high and 0.7 m wide. It pivots about a vertical edge and faces due south.
(Horizontal component of earths field is 20 micro tesla, vertical is 50 micro tesla)
Calculate the magnetic flux through the closed window (not a problem, 18Wb)
The window is opened through an angle of 90 degrees in a time of 0.8s
calculate the emf induced
Before you ask this is NOT homework but a question that i am having loads of problems with. I tried thinking of it as a volumetric shape (a quater of a cylinder). I tried thinking about emf's canceling out on the shape etc....
Thanks
