In figure, a magnetic flux of F is generated with a constant current of i. The core material used has a relative permeability of 2000. Assuming that the mean cross sectional area that the magnetic flux passing through in core and "part B" is A=4 [cm²Jand
there is a fringing of 5% in air gaps, N= 400 [turns] and i= 20 [A],
• what is the reluctance of the core?
• what is the reluctance in each air gap?
• what is the equivalent reluctance of the magnetic circuit?
what are the magnetic flux through the core and the magnetic flux density through each air gap?
• what is the force generated on "part B" in each air gap?
Remember: Ho= 4xx10, F = (s)² µ0 A / (2.P)
