NAME FOUR IMPORTANT PROBLEMS OF BAR MAGNET?

  • Bar Magnets like other magnets can loose their properties if they are heated, hammered or dropped from some height.
  • Bar Magnets become weak if they are not stored properly.(To keep them safe, bar magnets should be kept in pairs with their unlike poles on the same side. They must be separated by a piece of wood while two pieces of soft iron should be placed across their ends) 
  • Like other magnets, the magnetic field generated by a bar magnet can damage electronic equipment. A bar magnet placed near a hard drive, computer disk, or even a video cassette can cause the data stored by the magnetic particles on the item to be damaged.
