A cast steel electro magnet has an air gap length of 3mm and an iron path of length 40cm. Find the number of ampere turns necessary to produce a flux density of 0.7wb/m^2 in the air gap. Neglect leakage. Assume ampere turns required for air gap to be 70% of the total ampere turn.

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
