1.	The air-gap flux density waveform has decreased flux under one pole tip and measured under the other is due to __________(a) cross magnetization(b) magnetization(c) demagnetization(d) saturation of iron magnetic circuitThe question was asked in an interview for job.My doubt is from MMF and Flux Density Waveforms in DC Machines in portion DC Machines of Electrical Machines
Answer» RIGHT choice is (a) CROSS magnetization For explanation: The FLUX density increases under one pole tip while it decreases under the other due to the saturation of IRON MAGNETIC circuit.
