(b) A magnetic circuit is as shown in Figure 2, where f, is the force exerted on the movable part. Each of the fixed and movable parts has a cross-sectional area of 12 cm2. The fixed part has a winding of 200 turns. Determine the supply voltage V, required to keep the movable part at a distance of x = 1.5 mm from the fixed part if R, = 25 N and the magnetic force acting on the movable part is f, =167 N. Also, determine the energy stored in the magnetic field for x =1.5 mm. The permeability of free space u, is 47 x 107 H/m. You may neglect the reluctances of the fixed and moveable parts in your calculations. %3D Fixed part Movable part R, V,

(b) A magnetic circuit is as shown in Figure 2, where f, is the force exerted on the movable part. Each of the fixed and movable parts has a cross-sectional area of 12 cm?. The fixed part has a winding of 200 turns. Determine the supply voltage V, required to keep the movable part at a distance of x = 1.5 mm from the fixed part if R, = 25 N and the magnetic force acting on the movable part is f, = 167 N. Also, determine the energy stored in the magnetic field for x = 1.5 mm. The permeability of free space 4, is 47 x 10-7 H/m. You may neglect the reluctances of the fixed and moveable parts in your calculations. Fixed part Movable part R, V,
