The loadstone; a species of iron ore (the ferrosoferric or magnetic ore, Fe3O4) which has the property of attracting iron and some of its ores, and, when freely suspended, of pointing to the poles; -- called also natural magnet.
A bar or mass of steel or iron to which the peculiar properties of the loadstone have been imparted; -- called, in distinction from the loadstone, an artificial magnet.
An object surrounded by a magnetic field that has the ability to attract iron or steel.
attracts wealth and success in all endeavors
Specifically, a body possessing the property of attracting to itself particles of iron. More generally, a material capable of maintaining within and about itself a field of magnetic force.
Objects that are able to attract iron
a metal that has the property of attracting ferrous and certain other metals to it.
A piece of magnetized steel that will attract all ferrous material. The permanent magnet does not need electricity to function and will retain its magnetism over a period of years. Often shaped into the letter "U." Also see alnico magnet and permanent magnet.
A body which produces a magnetic field. All magnets are di-pole and follow the rule that like poles repel and unlike poles attract.
A body that attracts ferromagnetic materials. Can be a Permanent magnet, Temporary Magnet, or Electromagnet.
A body that attracts iron and other specific materials, because of a surrounding field of force produced by the motion of its atomic electrons and the alignment of its atoms.
A device which has the ability to attract or repel pieces of iron or other magnetic material. Speaker magnets provide a stationary magnetic field so that when the coil produces magnetic energy, it is either repelled or attracted by the stationary magnet.
The magnetic field among and between planets, brought out from the Sun by the solar wind.
(physics) a device that attracts iron and produces a magnetic field
a characteristic that provides pleasure and attracts; "flowers are an attractor for bees"
a body that attracts iron or steel
a body which attracts iron, combinations of metals (known as alloys) or other materials which are composed of iron or iron-like substances
a metal that attracts metals such as iron and other materials
an example of an attractor- a key complexity concept
an object or material that attracts certain metals, such as iron, nickel and cobalt
an object that can push or pick up materials made of iron, steel, or nickel
an object that has a Magbet ic field
an object that will pick up or attract things containing iron or steel
a piece of metal that attracts iron and certain other materials
a piece of metal that can attract other pieces of metal
a piece of metal that has the property of attracting another metal
a school or program within a school that attracts students Districtwide
a stone or piece of metal that has the property, either natural or induced, of attracting iron, nickel or steel
a very powerful attractor, but it is of no use if you want to get lint off your jacket
_A piece of magnetic material, e.g. iron, nickel or cobalt, that has been magnetized end is therefore surrounded by a magnetic field.
Steel or other magnetic material that has been magnetized. A permanent magnet will hold its magnetization indefinitely. Used in loudspeakers to provide the static magnetic field within which the voice coil operates. See Voice Coil, Electromagnet.
A magnet is an object made of certain materials which create a magnetic field. Every magnet has at least one north pole and one south pole. By convention, we say that the magnetic field lines leave the North end of a magnet and enter the South end of a magnet. This is an example of a magnetic dipole ("di" means two, thus two poles). If you take a bar magnet and break it into two pieces, each piece will again have a North pole and a South pole. If you take one of those pieces and break it into two, each of the smaller pieces will have a North pole and a South pole. No matter how small the pieces of the magnet become, each piece will have a North pole and a South pole. It has not been shown to be possible to end up with a single North pole or a single South pole which is a monopole ("mono" means one or single, thus one pole).
device attached to a crane, which is used for lifting scrap iron.
There are two magnets in the system: one in the coil and the other in the implant case. Together the two hold the coil in place on the head. The implant center audiologist can adjust the magnetic strength of the coil.
A combination of magnetic material and connected field concentrators that creates the magnetic field within which the speaker voice coil interacts to produce sound (see voice coil below). Magnetic materials have changed greatly over the years to produce much higher concentrations of magnetic fields with lighter and smaller volumes of material.
Material containing the property of attaining iron or steel and also produces an exterior magnetic field of energy.
Body that can be used to attract or repel magnetic materials.
A substance that attracts ferromagnetic materials. Either a permanent magnet, temporary magnet, or an electromagnet.
a piece of iron or other material that attracts other pieces of iron or steel
Steel or other magnetic material that creates the static magnetic field within which the voice coil operates to produce sound.
a piece of iron or other material that has a pulling force; this pulling force is called magnetism
An object, as a piece of iron or steel that possesses the property of attracting certain substances. The magnet used in MRI aligns the patient's hydrogen atoms so they are pointing in the same direction. Pulses of very specific radio wave frequencies are then used to vibrate these hydrogen atoms back and forth between their resting (magnetised) state and their agitated (radio pulse) state. The MRI equipment records the duration, strength, and source location of the signals emitted by the atoms as they relax and translates the data into an image on a PC screen.
A piece of material that has the natural ability to attract iron.
A body having the capability of attracting iron and producing a magnetic field external to itself.
A ferrite material charged to maintain a constant magnetic field.
The device at the back of a speaker that provides a stationary magnetic field to attract or repel the voice coil as the signal passes through it.
Any object or material that attracts iron and common steel.
A magnet is an object that has a magnetic field. It can be in the form of a permanent magnet or an electromagnet. Permanent magnets do not rely upon outside influences to generate their field.
