A ferromagnetic core is shown in the figure. The depth of the core is 5 cm. The
other dimensions of the core are shown. Calculate the magnetomotive force (in
Amp-Turns) required to produce a flux of 0.003 Wb. ur = 1000. Assume that the
mean path length of the flux is in the center of each leg of the core and ignore
the spreading at the corners of the core. Express your answer in whole number.
A ferromagnetic core is shown in the figure. The depth of the core is 5 cm. The
other dimensions of the core are shown. Find the value of the current (in
Amperes) that will produce a flux of 0.003 Wb. ur = 100o. Assume that the mean
path length of the flux is in the center of each leg of the core and ignore the
spreading at the corners of the core. Express your answer to two decimal places.
