Question: By taking a central flux path, estimate the inductance of the sensor shown in Figure (a) for zero air gap; (b) for a 2 mm

By taking a central flux path, estimate the inductance of the sensor shown in Figure

(a) for zero air gap;

(b) for a 2 mm air gap. Assume the relative permeability of core and armature is 104 and that of air is unity.

2.0 cm 200 turns 1.0 cm 3.0 cm 6.0cm 1.5 cm 3.0 cm 0.2 cm.

2.0 cm 200 turns 1.0 cm -3.0 cm- 6.0cm 1.5 cm 3.0 cm 0.2 cm
