Document Summary

Magnetic force: an attraction or repulsion transmitted by a field around magnetic o(cid:271)je(cid:272)ts (cid:894)(cid:858)(cid:373)ag(cid:374)ets(cid:859)(cid:895) All magnets have 2 poles (n and s); like poles repel and opposite poles attract. Causes force to weaken more rapidly with distance than gravity and electric force. So, when we say an object is magnetic we say that it possesses a magnetic field around it. Also, like the ef, the mf comes in 2 forms, or 2 poles, and we call these the magnetic n pole and then there is the magnetic s pole. These poles attract each other when opposite and the pulls repel when alike. Mf will align itself so that its n pole points in the direction of the surrounding fields s pole. The (cid:374)et result, all the (cid:272)o(cid:373)passes tra(cid:272)e out the field li(cid:374)es arou(cid:374)d the bar magnet. Another way that the mf differs from the ef is in the strength in the force, remember that the.
