Rule on these bar magnet claims

Read exercise and reference answers
Questions
  1. Statement is true
    Yes
    Statement
    Cutting a bar magnet across halves the dipole moment of each piece.
  2. Statement is true
    No
    Statement
    Cutting a bar magnet across also halves its pole strength.
  3. Statement is true
    Yes
    Statement
    A permanent magnet does not lose its magnetism.
  4. Statement is true
    No
    Statement
    Like poles attract each other and unlike poles repel.
  5. Statement is true
    Yes
    Statement
    A freely suspended magnet settles pointing north and south.
  6. Statement is true
    Yes
    Statement
    If one end has pole strength plus m the other has minus m.
  7. Statement is true
    No
    Statement
    A magnet pulls every kind of metal towards itself.
Instructions
Tap true or false for each claim about a bar magnet and about cutting one across.
