![1.120 pts) Three resistors are placed in a circuit as shown. What is the equivalent resistance between the points A and B? 60Ω 30Ω 2. 115 pts] A ring made of conductor swings across a region with uniform magnetic field B pointing into the paper as shown in the figure. Five positions are selected for a single swing from the left to the right. a. At which of the 5 positions, the magnetic flux is 0? 5 1, 2, 3, 4, 5 At which of the 5 positions, the flux is the maximum? 1, 2, 3, 4, 5 At which of the 5 positions, there is an induced current in the ring? 1, 2, 3, 4, 5 b. c. 3. 115 ptsl The drawing shows a cube. The dashed lines in the drawing are perpendicular to faces 1, 2, and 3 of the cube. Magnetic fields are oriented with respect to these faces as shown, and each of the three fields, B, B, and B, has the same magnitude. Note that B: is parallel to face 2 of the cube. Rank the magnetic fluxes that pass through the faces 1, 2, and 3 of the cube in decreasing order (largest first): [Hint: Φ BA cosp, A is the area of the surface)](http://img.homeworklib.com/questions/56f3bbf0-c818-11ea-90cc-c56bc9dc804d.png?x-oss-process=image/resize,w_560)

Problem 5:
Consider the four cubes shown to the right, numbered 1 through 4.
Three of the faces of each cube are labeled A, B, C.
surface 2B attracts surface 4A
surface 1A attracts surface 4C
surface 3B does not interact with 1A
Determine if each of the cubes is a magnet, a
ferromagnet or non-magnetic. Explain. If you cannot determine which
class a cube belongs to, explain why you cannot.
