A current I1 of 1 A and a current I2 of 2 A are applied to a magnetic core with a relative permeability of 2100, where the number of turns of the winding is 1000. The depth of the magnetic core is 20 cm, in addition Take into account that the bounded measurements are given in centimeters. The air gap shown in the figure is 0.2 cm and has an effective area equivalent to 1.1 times the cross-sectional area of ??the core.

Determine:
a) The equivalent circuit with sources and reluctance (graph it)
b) The magnetic flux of the central column
c) Magnetic induction at point A
d) Explain what would happen if the flow of current I1 is reversed.
