magnet

 [mag´net]
an object having polarity (oppositely charged ends) and capable of attracting iron.

mag·net

(mag'net),
1. A body that has the property of attracting particles of iron, cobalt, nickel, or various other metallic alloys and that, when freely suspended, tends to assume a definite direction between the magnetic poles of the Earth (magnetic polarity).
2. A bar or horseshoe-shaped piece of iron or steel that has been made magnetic by contact with another magnet or, as in an electromagnet, by passage of electric current around a metallic (iron) core.
3. An electromagnet built in a cylindrical configuration to accommodate a patient in its core, for magnetic resonance imaging.
[G. magnēs]
An iron-based mass or bar with magnetic polarity
