Question 7 A magnetic core is shown in Figure 1. Relative permeability of the core is 14 = 2000. Total number of winding turns in the left winding is NL = 100 and in the right winding is Nr = 10. Assume that the core cross section is uniform and the combined length of all air-gaps is much smaller than the dimensions of the core cross-section. Calculate the following: a) The magnetomotive force in the core if i = 2...

In the figure below, block-2 of mass M = 1 Kg is at rest on a frictionless surface and touching the end of an un-stretched spring whose spring constant is 200 N/m. The other end of the spring is fixed to a wall. Block-1 of mass 2 Kg, travelling at speed v_1 = 4 m/s, collides with block-2 and the two blocks stick together. When the blocks momentarily stop, by what distance is the spring compressed?
