What the Magnet Is Used to Show
Two such magnets show that unlike poles attract and like poles repel. Hung from a thread, one settles with its red end towards the north, which is how the north pole gets its name. Under a sheet of paper with iron filings, or traced point by point with a plotting compass, it gives the familiar pattern of field lines running from N round to S; with two like poles facing each other, a neutral point appears between them where the fields cancel.
Why the Keepers Matter
Left on its own, a bar magnet slowly loses strength because its own field works against the magnetisation. Store two magnets side by side with unlike poles together and a keeper across each end, which closes the magnetic circuit and holds their strength. Dropping or heating the magnet also weakens it.
