A long straight wire passes through a piece of card. There is a current in the wire, as shown in Fig. 11.1.

18-32-8b

Fig. 11.2 shows the view of the card from above. The current is into the page.

18-32-8c

The current in the wire produces a magnetic field around the wire. One magnetic field line is drawn.

 
On Fig. 11.2, draw two more magnetic field lines around the wire. Show the direction of the magnetic field by drawing an arrow on each field line.

2b1 mark

Apart from an electric door bell, suggest another use for electromagnets.
