QUESTION 22.1The magneto coil of a car rotates at 1300 rpm. The coil has 80 windings anda length and width of 70 mm and 90 mm respectively. The pole shoe has anarea of 0.4 m? and it moves through a magnetic flux of 35 mWb. Determinethe induced emf.2.2Draw a pole shoe of a DC Machine and show the field winding. Use this toinvestigate if the dimensions of the coil in 2.1 above is realistic w.r.t the shoearea. If you feel it is unrealistic recommend better dimensionsIs it a necessity to get both the coil dimensions and the shoe area for thecalculation in 2.12.3The mutual inductance of two coils A and B, wound on a common core is 20 H.If the current in coil A varies from 3 A to 15 A in 200 ms. Calculate:I.the emf in coil BII. the change in the flux of B if coil B has 200 turns
