Solved by Expert Surendra Kumar

Step 1

First, we need to calculate the total magnetic flux (Φ) passing through the steel path. We can use the formula Φ = B * A, where B is the magnetic flux density and A is the area through which the flux must flow. Given that the area through which the flux must flow Show more…

QUESTION THREE (20 MARKS) The diagram below shows the layout of an electric motor stator and rotor through which magnetic flux must flow. The area through which the flux must flow is 0.004 mÂ². The average length of the steel path is 0.32 m. The length of each air gap is 1 mm. The steel used has Î¼ = 2000. If the steel path has 1000 turns of copper wire wound onto it and the wire carries 10 A, calculate the magnetic flux density (B) in the air gap.
