Magnetic Circuits y Part A - Calculate reluctances Learning Goal: To understand how magnetic structures can be analyzed by drawing an equivalent circuit, and to use the equivalent circuit to calculate magnetic fluxes and coll currents. When analyzing magnetic structures, the geometry is often complex enough that using the fundamental rules can be very difficult without numerical methods. However, there are approximate methods that are often sufficient for engineering calculations. When the magnetic field is mostly contained within cores of...

Group Problem 2: You are given the task to determine the inductance M of two inductors of unknown self-inductances L1 and L2. Recall that M = M12 = M21 and the magnetic flux B1,2 = M12/1 and B2,1 = M2112. To perform this task, you connect one of the inductors (say L1) in series with a battery of emf = 10 V and a resistor of resistance R1 = 212. These three components, as well as a switch S, form...

Explain what effect the following scenarios would have on the calculated specific heat (i.e. would it be calculated artificially high, low, or have no effect). Your explanation should address what variable(s) would be affected by the scenario and how that affects the calculation of specific heat.(1.5pt each) A student accidently dropped the piece of metal on the countertop during the process of transferring it from the boiling water bath to the calorimeter, but was quickly picked up and put into...
