A ferromagnetic core is shown in Figure PI- 2. The depth of the core is 5 cm. The
other dimensions of the core are as shown in the figure. Find the value of the current
that will produce a flux of 0.005 Wb. With this current. what is the flux density at
the top of the core? What is the flux density at the right side of the core? Assume
that the relative permeability of the core is 1000.
