Question 9 (Page 76) While a mechanic was repairing a gadget using a screw driver, the steel screws kept falling down. Suggest a way to solve the problem of the mechanic on the basis of what you have learnt in this chapter .The mechanic can magnetize the screwdriver by rubbing one pole of a bar magnet along its length several times in the same direction. As a result, the screwdriver becomes a temporary magnet. The screws will now stick to its tip, preventing them from falling while the mechanic works.
