Which of the following is not true about simple magnets?

62% Answer Correctly

opposite poles repel each other

all of these are untrue


Solution

Simple magnets have two poles, north and south, and opposite poles attract each other (N attracts S, S attracts N). Likewise, the same pole of two magnets repel (N repels N, S repels S). The Earth has a magnetic field and North and South Poles which enables the use of a magnetic compass to determine direction.
