- Safety pins
WHAT TO DO :-
Pick up one of the safety-pins with the magnet and then draw the safety-pin to the second one. After holding the three together, retract the magnet.
WHAT HAPPENS :-
The first safety-pin attracts the second and and remains fixed to it even after the magnet has been withdrawn.
WHY THIS HAPPENS :-
This happens because after the safety-pin makes contact with the magnet, it becomes magnetized, therefore making the safety-pin work like a magnet on the other one.
With the magnet try and see if you can magnetize other objects like pieces of wood, paper pins and other objects at home. This will give you a better understanding into what can turn magnetic and what cannot.
