Q5. [20 marks] Consider the setup shown in Fig. Q5. Determine the minimum amount of current required to keep the magnetic plate at a distance of (2.Y) mm from the pole faces of an electromagnet having (100X) turns when the torque exerted by the spring at an effective radius of 20 cm is 20 N-m. Assume each pole face has a circular cross section with a diameter of 3 cm. Consider the relative permeability of magnetic material and magnetic plate as infinity. Magnetic plate 4 20 cm cm (100X) turns cm air-gap Figure Q. 5. Spring
