3 Fg. 8.1 shows a vertical current-carrying wire passing through a card at point x. card current direction Fig. 8.1 (a) On Fig. 8.1, sketch on the card the pattern of the magnetic field produced by the current in the wire. The detail of your sketch should suggest the variation in the strength of the field. Show the direction of the field with arrows (b) Using your knowledge of investigating the magnetic field around a bar magnet, suggest an experiment or experiments to confirm that you have drawn the correct pattem and direction in (a).
