1.	What is the formula for the magnetizing current?(a) magnetizing current = total mmf * number of turns(b) magnetizing current = total mmf / number of turns(c) magnetizing current = total mmf + number of turns(d) magnetizing current = total mmf – number of turnsI got this question during an online exam.I'd like to ask this question from Specific Permeance & Calculation of Magnetizing Current topic in section Principles of Magnetic Circuit Design of Design of Electrical Machines
Answer» RIGHT answer is (b) magnetizing current = total mmf / number of turns The best EXPLANATION: FIRST the total mmf is calculated along with the number of turns of the magnetizing winding. Then on substitution the magnetizing current is obtained.
