diamagnetic    音标拼音: [d,ɑɪəmægn'ɛtɪk]
a. 反磁性的
n. 反磁性体

反磁性的反磁性体

diamagnetic
抗磁性的

diamagnetic
adj 1: relating to or exhibiting diamagnetism; slightly repelled
by a magnet

Attraction \At*trac"tion\, n. [L. attractio: cf. F. attraction.]
1. (Physics) An invisible power in a body by which it draws
anything to itself; the power in nature acting mutually
between bodies or ultimate particles, tending to draw them
together, or to produce their cohesion or combination, and
conversely resisting separation.
[1913 Webster]

Note: Attraction is exerted at both sensible and insensible
distances, and is variously denominated according to
its qualities or phenomena. Under attraction at
sensible distances, there are, -- (1.)

{Attraction of gravitation}, which acts at all distances
throughout the universe, with a force proportional
directly to the product of the masses of the bodies and
inversely to the square of their distances apart. (2.)

{Magnetic}, {diamagnetic}, and {electrical attraction}, each
of which is limited in its sensible range and is polar in
its action, a property dependent on the quality or
condition of matter, and not on its quantity. Under
attraction at insensible distances, there are, -- (1.)

{Adhesive attraction}, attraction between surfaces of
sensible extent, or by the medium of an intervening
substance. (2.)

{Cohesive attraction}, attraction between ultimate particles,
whether like or unlike, and causing simply an aggregation
or a union of those particles, as in the absorption of
gases by charcoal, or of oxygen by spongy platinum, or the
process of solidification or crystallization. The power in
adhesive attraction is strictly the same as that of
cohesion. (3.)

{Capillary attraction}, attraction causing a liquid to rise,
in capillary tubes or interstices, above its level
outside, as in very small glass tubes, or a sponge, or any
porous substance, when one end is inserted in the liquid.
It is a special case of cohesive attraction. (4.)

{Chemical attraction}, or

{affinity}, that peculiar force which causes elementary
atoms, or groups of atoms, to unite to form molecules.
[1913 Webster]

2. The act or property of attracting; the effect of the power
or operation of attraction. --Newton.
[1913 Webster]

3. The power or act of alluring, drawing to, inviting, or
engaging; an attractive quality; as, the attraction of
beauty or eloquence.
[1913 Webster]

4. That which attracts; an attractive object or feature.
[1913 Webster]

Syn: Allurement; enticement; charm.
[1913 Webster]


Diamagnetic \Di`a*mag*net"ic\, n.
Any substance, as bismuth, glass, phosphorous, etc., which in
a field of magnetic force is differently affected from the
ordinary magnetic bodies, as iron; that is, which tends to
take a position at right angles to the lines of magnetic
force, and is repelled by either pole of the magnet.
Contrasted with {paramagnetic} and {ferromagnetic}.
[1913 Webster]


Diamagnetic \Di`a*mag*net"ic\, a.
Pertaining to, or exhibiting the phenomena of, diamagnetism;
taking, or being of a nature to take, a position at right
angles to the lines of magnetic force. See {Paramagnetic}.
[1913 Webster]

{Diamagnetic attraction}. See under {Attraction}.
[1913 Webster]

  • Diamagnetism - Wikipedia
    Diamagnetism is the property of materials that are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force In contrast, paramagnetic and ferromagnetic materials are attracted by a magnetic field
  • Paramagnetic vs Diamagnetic vs Ferromagnetic – Magnetism
    Diamagnetic materials do not retain magnetic properties when the external magnetic field is removed In other words, there is no permanent magnetic effect Because they repel a magnetic field, diamagnetic substances levitate over a magnetic field
  • Diamagnetism: Definition, Cause, and Examples - Science Facts
    Diamagnetism is a property exhibited by certain materials, known as diamagnetic materials, that cause them to create a weak magnetic field in the opposite direction when placed in an external magnetic field
  • What Does Diamagnetic Mean in Chemistry? - ThoughtCo
    A diamagnetic substance does not have unpaired electrons and is not attracted to a magnetic field All materials display diamagnetism, but to be diamagnetic, this must be the only contribution to its magnetic behavior Examples of diamagnetic materials include water, wood, and ammonia
  • Magnetic Fields, Superconductors Levitation - Britannica
    Indeed, all substances are diamagnetic: the strong external magnetic field speeds up or slows down the electrons orbiting in atoms in such a way as to oppose the action of the external field in accordance with Lenz’s law
  • Ferromagnetic Vs. Paramagnetic Vs. Diamagnetic - Stanford Magnets
    It is common to use the terms ferromagnetic, paramagnetic, or diamagnetic to describe how a material responds to a magnetic field Ferromagnetic materials are attracted strongly to both magnet poles Paramagnetic materials are only faintly drawn to one pole
  • Diamagnetism - Engineering LibreTexts
    Essentially, diamagnetic behavior is the change in orbital angular momentum induced by an external magnetic field [1] All materials exhibit a diamagnetic response, and it may be understood as the attempt to expel the applied magnetic field
  • Diamagnetic Materials | Properties, Uses Examples
    Diamagnetic materials are a fascinating class of materials in the field of materials science and physics They are characterized by their weak negative magnetic susceptibility, meaning they repel magnetic fields
  • Diamagnetism: Definition and Examples - samaterials. com
    Diamagnetism is a fundamental property of materials that causes them to create an opposing magnetic field when exposed to an external magnetic field Unlike other forms of magnetism, diamagnetism is a universal property present in all materials, though it is usually very weak
  • 12. 4: Diamagnetism - Physics LibreTexts
    Diamagnetic materials have a very weak negative susceptibility All materials are diamagnetic, even if their diamagnetism is hidden by their greater para- or ferromagnetism
