The magnetic circuit shown in Figure above consists of a laminated core of USS Trans-former 72, 29-gauge steel with an air gap g of 6 mm and an exciting winding of 1,000 turns. The stacking factor for the core is given to be 0.94. Neglect leakage but correct for fringing by adding the length of the air gap to each of the other two dimensions of the cross section. The dc magnetization characteristic for USS Transformer 72, 29-gauge steel is given in Figure. Determine the current in the exciting winding that produces a core flux of 1 X 10-³ Wb.

Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.
