An electrical conductor is placed between the poles of a magnet as shown in . electrical conductor N pole S pole State a material from which an electrical conductor can be made. A centre-zero meter measures the electromotive force (e.m.f.) across the conductor. State the unit of e.m.f. unit = State what, if anything, is shown by the centre-zero meter when the conductor is moved. • horizontally, from side-to-side, between the poles of the magnet, • vertically, up-and-down, between the poles of the magnet. State two factors that affect the size of the e.m.f. across the conductor.

State what is meant by the north pole of a magnet. The north poles of two magnets are brought close together. What sort of force, if any, is there between the poles? Tick one box. attractive repulsive no force shows the north pole of a magnet close to an iron bar. The iron bar is attracted to the north pole because of induced magnetism in the iron bar. On , mark clearly the induced north pole and the induced south pole of the iron bar. State what happens to the induced magnetism in the iron bar when the magnet is taken away. N magnet iron bar Use

Four rods are shown in . plastic rod iron rod wooden rod brass rod State which of these could be held in the hand at one end and be magnetised by stroking it with a magnet, charged by stroking it with a dry cloth. Magnets A and B in are repelling each other. magnet A N magnet B The north pole has been labelled on magnet A. On , label the other three poles. Charged rods C and D in are attracting each other. rod C + rod D On , show the charge on rod D. shows a plotting compass with its needle pointing north. N A brass rod is positioned in an east-west direction. A plotting compass is put at each end of the brass rod, as shown in . N brass rod plotting compass On , mark the position of the pointer on each of the two plotting compasses.
