  • Interesting fact: Earth's magnetic field has been weakening. It seems to have lost 15% of its strength since 1670. At the present rate of decrease, it will reach zero in 2,000 years. Between the years 3500 and 4500, the magnetic field will not be sufficiently strong enough to ward off charged radiation from outer space.
    • Magnetism Power of attraction; power to excite the feelings and to gain the affections.
    • n Magnetism The property, quality, or state, of being magnetic; the manifestation of the force in nature which is seen in a magnet. At one time it was believed to be separate from the electrical force, but it is now known to be intimately associated with electricity, as part of the phenomenon of electromagnetism.
    • Magnetism The science which treats of magnetic phenomena.

  • Interesting fact: Every eleven years the magnetic poles of the sun switch. This cycle is called "Solarmax".
    • n magnetism That peculiar property occasionally possessed by certain bodies (more especially by iron and steel) whereby, under certain circumstances, they naturally attract or repel one another according to determinate laws. According to the molecular theory of magnetism, the molecules of a magnetic substance possess permanent polarity, and as it is more and more highly magnetized the poles are arranged more and more perfectly in a common direction; when it is magnetized to the highest degree possible—that is, to saturation—all the north poles of the molecules point in one direction and all the south poles in the opposite direction. On this theory coercive force is simply that condition of the substance which retards this molecular arrangement during the process of magnetization and tends to retain it after magnetization. The current theory, or Ampère's theory of magnetism, supposes each molecule to be traversed by a closed electric circuit; these currents become parallel upon magnetization, and may then be regarded as equivalent to a series of closed electric currents about the exterior of the bar, these currents being clockwise at the south pole and counter-clock-wise at the north pole. This theory derives its support from the observed fact that a spiral conductor traversed by a current (a solenoid) behaves as a magnet in all respects, being directed similarly by the earth and having a similar field of force about it. See magnet.
    • n magnetism That branch of science which treats of the properties of the magnet, and of magnetic phenomena in general.
    • n magnetism Attractive power; capacity for exciting sympathetic interest or attention: as, the magnetism of eloquence; personal magnetism.
    • n magnetism See mesmerism and hypnotism.

  • Interesting fact: Public telephones in Israel are no longer operated by tokens as they were in the past. They are now operated by magnetic cards known in Hebrew as a telecart (tel-eh-cart). These plastic cards, the same size and shape as a credit card, are available at post offices, some hotel reception desks, street kiosks and dispensing machines.

But Love is mightier far, than Fear:
The ladye hasteth not:
The magnet of her heart is near,
And peril is forgot!

Which invites the soul to rise;
Be a helm my thoughts to steer,
To thy ever tranquil sphere.

While Heaven supplies each innocent request;
And lo! what fond regard their smiles reveal,
Attractive as the magnet to the steel.

How it is I know not—yet behold! the something which obeys none of
the rest,
It is offensive, never defensive—yet how magnetic it draws.

The trembling that thou joinest with our mirth,
Are but thy magnet-communings compelling
Our spirits farther from the scope of earth.

Despite a life ascetic,
And from the narrow path of right
I felt a tug magnetic,
That sought to draw me o'er the sand
Out to the siren-haunted strand.
