Iron which is brought near a spiral of copper wire, traversed by an electrical current, becomes magnetic, and then attracts other pieces of iron, or a suitably placed steel magnet.
Sentiment: POSITIVE
Magnetism, as you recall from physics class, is a powerful force that causes certain items to be attracted to refrigerators.
Electricity, the peril the wind sings to in the wires on a gray day.
Some minds improve by travel, others, rather, resemble copper wire, or brass, which get the narrower by going farther.
According to well-known electrodynamic laws, an electron moving in a magnetic field is acted upon by a force which runs perpendicular to the direction of motion of the electron and to the direction of the magnetic field, and whose magnitude is easily determined.
The transitions from metallic to critical behavior and from critical to insulating behavior have been induced with a magnetic field, and from insulating to critical and then to metallic behavior with increasing external pressure.
A grocer is attracted to his business by a magnetic force as great as the repulsion which renders it odious to artists.
We studied the light source in the direction of the magnetic force, we perforated the poles of the magnet; but even in the direction of the magnetic lines of force we found that our result was confirmed.
Just luxuriate in a certain memory, and the details will come. It's like a magnet attracting steel filings.
I have been making wire jewelry - and think I'll really do something with it, eventually.
We believe that electricity exists, because the electric company keeps sending us bills for it, but we cannot figure out how it travels inside wires.
