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. ↗

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. ↗

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 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. ↗

For in 1900 all electromagnetic radiation of longer wavelengths was already known at least to the extent that one could not seek in it the more striking characteristics of X-rays such as, for example, the strong penetrating power. ↗

Listening is a magnetic and strange thing, a creative force. The friends who listen to us are the ones we move toward. When we are listened to, it creates us, makes us unfold and expand. ↗

I think it has sullied his presidency. As brilliant a politician as Bill Clinton is, as magnetic a personality as he can be, there is one little screw loose somewhere. ↗
