Что такое магнитная аномалия? Почему в области магнитной аномалии показания компаса неверны?

1,Чрезвычайно сильное магнитное поле в некоторых областях земной поверхности; потому что его стрелка перестает там свободно поворачиваться

2,Отклонение стрелки компаса от магнитной линии магнитного поля Земли в данном месте; по той же причине

3,Несоответствие картины магнитного поля той, которая должна быть в данном месте Земли; потому что местное магнитное поле действует на его стрелку

4,Постоянное необычно сильное магнитное поле на некоторых территориях Земли; потому что там находятся залежи железной руды, магнитное поле которой влияет на расположение магнитной стрелки компаса
