When heated, hammered or dropped from a height, magnets tend to lose their properties. They become weak if they are not stored properly and hence:
→ Bar magnets should be stored in pairs separated by a small block of wood and their unlike poles facing the same side with a soft iron across their ends.
→ A piece of iron should be kept across the poles in case of a horse shoe magnet.
→ Magnets should be kept away from computers, mobiles, televisions etc.
→ Magnets should be handled with care and they should be stored properly.
