CLICK HERE TO SEE QUESTION 4 4.1. The cоil оf аn AC generаtоr rotаtes at a constant rate in a magnetic field as shown below. 4.1.1. Explain briefly why an emf is induced in the coil. (2) 4.1.2. Draw a sketch graph showing emf against position for the coil, marking P, Q, R, S and T on the x-axis. (3) 4.2. The sketch below shows a simple dc motor. 4.2.1. Describe the energy conversion that takes place in the dc motor. (2) 4.2.2. Name the law used to predict the direction of rotation of the coil. (1) 4.2.3. Predict whether the coil will rotate clockwise or anti-clockwise. (2) 4.2.4. Name part A, and briefly describe its function and how it achieves this function. (4) 4.3. The magnetic field lines created by a current in a conductor are shown in the diagram. Is the conventional current direction from X to Y or Y to X? (2) 4.4. The coil and magnets illustrated in the diagram below could be part of a motor or a generator. 4.4.1. Describe the energy conversion that takes place in a generator? Is this energy conversion different or the same as the energy conversion that take place in a motor? (3) 4.4.2. Consider the coil in the above diagram to be part of a motor. The current direction is from P to Q in the coil. A. In which direction would side PQ experience a force? (2) B. How would you change two factors in order to increase the magnitude of the force exerted on side PQ? (2) C. A current carrying conductor placed in a magnetic field will not always experience a force. Describe a situation in which a current carrying conductor in a magnetic field will not experience a force. (2) 4.4.3. Consider the coil to be part of a generator. A. Define magnetic flux linkage. (2) B. Use Faraday's Law to explain why a current is induced in the coil as it rotated in the magnetic field. (4) C. State Lenz's Law. (2) D. As side PQ is rotated out of the page, will the current be induced from P to Q or from Q to P? (2) [35]
