1 Answer

Answer :

a. Magnet imparts its magnetic properties to other metals. b. When a magnet is suspended freely horizontally, it stands at geographical north and south. c. Every magnet has a north and its associated separable South Pole. d. If a magnet broken in any number of pieces, each piece will act as a separate magnet having north and south poles. e. Like poles repulse and unlike poles attracts. f. The amount of attraction or repulsion is directly proportional to the pole strength and inversely proportional to the square of the distance between them. This is some times known as inverse square law.
