Determine the necessary current in the coil to provide the \( 2.16 \mathrm{mWb} \) flux in the core of the magnetic circuit in Figure 18. The length of the cast steel path is \( 120 \mathrm{~mm} \). The crosssectional area of \( x x x \) is found through out the core. Ignore fringing in the gap. Use the \( \mathrm{B}-\mathrm{H} \) chart below to find the correct magnetizing force in the cast steel.
