Problem 1:
Consider the inductor with primary winding in red
secondary winding in purple shown on the right.
The purple wire goes across the air gap in the inductor
core.
I₁ = 1A
N = 400
turns
1₁ = 50 cm
Hr=3000
W
4 cm
h = 3 cm
d=0.05 cm
1₂ = 45A
Part a) Draw a magnetic circuit for this inductor. You may ignore any effects of the secondary (purple) winding.

Part b) Calculate the core and air gap magnetic reluctance.
Part c) For the primary current I₁ shown, calculate the flux, Þ. Indicate the direction of flux (with an arrow) on both
the magnetic circuit you drew for Part a) AND on the inductor drawing itself.
Part d) What is the force on the secondary winding? Indicate the direction of force (with an arrow) on the drawing.
