magnet

Noun
  1. (physics) a device that attracts iron and produces a magnetic field (synset 103710918)
    referred to in: natural philosophy, physics - the science of matter and energy and their interactions
    is a type of: device - an instrumentality invented for a particular purpose
    subtypes:
    • bar magnet - a magnet in the form of a bar with magnetic poles at each end
    • electromagnet - a temporary magnet made by coiling wire around an iron core; when current flows in the coil the iron becomes a magnet
    • field magnet - a magnet that provides a magnetic field in a dynamo or electric motor
    • magnetic needle - a slender magnet suspended in a magnetic compass on a mounting with little friction; used to indicate the direction of the earth's magnetic pole
    • paramagnet - magnet made of a substance whose magnetization is proportional to the strength of the magnetic field applied to it
    • permanent magnet, static magnet - a magnet that retains its magnetism after being removed from a magnetic field
    • solenoid - a coil of wire around an iron core; becomes a magnet when current passes through the coil
    has:
    • core - a bar of magnetic material (as soft iron) that passes through a coil and serves to increase the inductance of the coil
    • magnetic pole, pole - one of the two ends of a magnet where the magnetism seems to be concentrated
  2. A characteristic that provides pleasure and attracts (synset 105859350)
    "flowers are an attractor for bees"
    is a type of: characteristic, feature - a prominent attribute or aspect of something
    subtypes:
    same as: attracter, attraction, attractive feature, attractor
