1.	The leakage flux on the top of the slot is through iron, which is called ‘bridge’?(a) true(b) falseI have been asked this question by my school teacher while I was bunking the class.I'd like to ask this question from Determination of Iron Losses & Slot Leakage topic in portion Principles of Magnetic Circuit Design of Design of Electrical Machines
Answer» Correct choice is (a) true Easiest EXPLANATION: The leakage FLUX on the top of the slot is through IRON, which is called ‘bridge’. Therefore the specific permeance of this PATH depends upon the permeance of iron which in turn depends upon the degree of saturation and HENCE upon the relative permeability of iron.
