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. ↗

It was not simply out of a spirit of contradiction that I exposed a light source to magnetic forces. The idea came to me during an investigation of the effect discovered by Kerr on light reflected by magnetic mirrors. ↗

In the absence of a magnetic field the period of all these oscillations is the same. But as soon as the electron is exposed to the effect of a magnetic field, its motion changes. ↗

I remember the difficulty we had in the beginning replacing magnetic cores in memories and eventually we had both cost and performance advantages. But it wasn't at all clear in the beginning. ↗

Some may wonder whether part of the harvest of this invisible pollution (electromagnetic radiation) may be the comparative rarity of visionary experience in the modern world, and the predominence of a removed, overanalytical, repelling 'onlooker' intelligence in its place, resembling that of the (Martin) Amis hero (who will not see because he cannot feel). If this is so, such an intelligence has produced conditions favoring its evolution and survival. ↗

I joined the Army and was sent to the MIT radiation laboratory after a few months of introduction to electromagnetic wave theory in a special course, given for Army personnel at the University of Chicago. ↗

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. ↗

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. ↗

The application of a strong magnetic field enables the measurement of the energy of the most penetrating particles to be carried out, and the method may be capable of still further extension and improvement. ↗

The great thing about the United States and the historically magnetic effect it has had on a lot of people like me is its generosity, to put it simply. ↗
