Experiment-I (Permanent Magnetic):
Draw two lines at right angles to each other on the sheet ofpaper, then position the compass on it so that the pivot of thecompass needle lies directly above the point of intersection of thelines. Turn the sheet of paper until the compass needle lies alongthe shorter line and mark the ends of this line N and S (see Fig.4).
Place the bar magnet on the sheet of paper at about 10 cm fromthe compass needle and mark two field lines on the paper (Fig. 3and Fig. 4).
• Move the compass slowly once around the bar magnet along themarked field lines, observing the movement of the compass needle.Note what you observe under Result - Observation I-1.
