yes depends on what type of headphones and how strong the magnet is .
An object that attracts material containing iron and always faces the same direction when moving freely is lodestone. ---- Nickel and cobalt are two other metals, in addition to iron, that display this type of magnetism. If you wish more information it is available on the wikipedia article entitled 'magnet'.
Metals not magnetic, but permeable will become magnets when near or touching a permanent magnet. You can stroke some metals in the same direction repeatedly on a magnet and make it a magnet.
The force of attraction or repulsion between two magnetic materials.

Whenever there is a certain type of force, one that fulfills certain conditions (called a "conservative force") - such as a magnetic field, an electric field, or a gravitational field - there is an associated potential energy.
A dumbbell shaped magnet is called which type of magnet?
Lodestone is an example of a natural magnet.
An electro-magnet would be the strongest magnet. Or the sun itself would be the strongest natural magnet.
a permanent magnet does that.
Lodestone is the only example of a natural magnet.
