(a)[1]
Draw a ring around the statement that correctly describes the force between the magnets.
(b(i))[1]
When current flows through the solenoid, its ends behave like the poles of a bar magnet. Complete Table 10.1 by naming the pole at end A and the pole at end B.
(b(ii))[2]
On Fig. 10.3, draw the shape of the magnetic field created by the solenoid. Include at least two magnetic field lines above line AB and two below line AB.
(b(iii))[1]
Draw arrows on the field lines to indicate the direction of the magnetic field produced by the solenoid.
(c)[2]
State two reasons an electromagnet may be more useful than a permanent magnet.
