Part Two

The figure below shows a compass and a magnet. Label the poles of the magnet and draw the field lines on the magnet. Q#22

The three diagrams show the field lines between the poles of two magnets. Identify the poles A, B, C, D, E and F as north or south poles. Q#23

Label the poles of the solenoid below if the current flows in the wire in the direction shown. Q#24

Draw the meter reading that you would expect in each of the following cases: Q#25
