  • Ground Magnetic Surveys Seeing Beneath The Rocks

    Why Is A Ground Magnetic Survey Useful?Conducting A Ground Magnetic SurveyInterpreting A Ground Magnetic SurveyGround magnetic surveys map the magnetism of underlying rocks. The most common magnetic minerals found are pyrrhotite, (iron sulphide), and magnetite. Magnetite when found with sufficient purity and quantity may become an iron ore deposit.Pyrrhotite is important because of the minerals it’s often associated with including pyrite, another iron sulphide mineral, which may contain gold.

  • What Causes a Permanent Magnet to Lose Its Magnetism

    A magnet gets its field when microscopic magnetic areas, called domains, all line up in the same direction. When the domains cooperate, the magnet’s field is the sum of all the microscopic fields in it. If the domains fall into disorder, the individual fields cancel out, leaving the magnet weak.
