Where does a compass point when it is moved close to a magnet?
That depends on which pole of the magnet it is moved close to. If it is brought close to the "South" pole of the magnet, the "North" pointer of the compass will be attracted to the magnet. If it is brought close to the "North" pole of the magnet, the "North" pointer of the compass will be repelled and will point AWAY from the magnet, while the "South" end of the compass pointer will point to the magnet.
Where does the pointer of a compass always point?
