shows in each of the diagrams a current-carrying conductor and a magnetic field pattern. A B C current-carrying conductor current-carrying conductor current-carrying conductor State the diagram which correctly shows the magnetic field around a current-carrying conductor. shows three pieces of equipment. coil coil with 100 turns of wire sensitive centre-zero meter bar magnet S N Describe how to generate and detect an electromotive force (e.m.f.) using the equipment in . You may draw a diagram. Describe two changes that will generate a larger e.m.f. using similar equipment to that in . A student connects a lamp and centre-zero galvanometer in series with a generator, as shown in . lamp centre-zero galvanometer generator G The student observes the galvanometer needle moving from side-to-side repeatedly. Explain why the needle moves in this way.

Use Electromagnetic induction may be demonstrated using a magnet, a solenoid and other necessary apparatus. Explain what is meant by electromagnetic induction. In the space below, draw a labelled diagram of the apparatus set up so that electromagnetic induction may be demonstrated. Describe how you would use the apparatus to demonstrate electromagnetic induction. State two ways of increasing the magnitude of the induced e.m.f. in this experiment. 1. 2.
