Question 1 a) There is a relationship between the induced magnetic flux density B and the magnetizing force H (i) Discuss this relationship? (ii) Explain the Hysteresis Loop/Curve? What is the best material for motor magnet, Explain? b) If a solenoid is free to turn about the vertical direction and a uniform horizontal magnetic field of 0.25 T is applied, and its axis makes an angle of 30° with the direction of applied field. The number of turns is 800, the current passing the solenoid is 3 A, and the cross-section area is 2.5x104 m² (i) Draw the solenoid and the magnetic field? (ii) Identify the magnitude of torque on the solenoid? Explain the working principal?
