the hollow cylinder shown in fig 2.2 (see attachment) is free to rotate on a horizontal axis. one hole is cut in the side of the cylinder. the object of the game is to spin the cylinder so fast that the object dropped through the hole when it is in the uppermost position will fall through the...
The magnetic field is B. There is no numerical value. The rectangle is circumscribed within the solid loop of radius R1 and R2, therefore, the magnetic field also passes through the loop; but only through the rectangle...nowhere else. I will tell you this, the two radii confused me at first. I...
The only location the magnetic field passes through is the through the rectangle. Since there isn't a uniform magnetic field passing through the hoop, you have to use the definition flux=int B dA.
Here is the problem: You have a loop of radius r1 and r2. You have a rectangle with dimensions of length a and b (b>a) with a uniform magnetic field only passing through this rectangle, into the page. What is the magnetic flux through the loop? To better help visualize the diagram, the length b...
Hi, guys. In a previous post this problem was given: Let B be a solid box with length L, width W, and height H. Let S be the set of all points that are a distance at most 1 from some point of B. Express the volume of S in terms of L,W, and H. How do you attack this problem? I'm not sure where to...
