A Quote by Pieter Zeeman

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.
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.
What lead me more or less directly to the special theory of relativity was the conviction that the electromotive force acting on a body in motion in a magnetic field was nothing else but an electric field.
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.
I would not give my rotating field discovery for a thousand inventions, however valuable... A thousand years hence, the telephone and the motion picture camera may be obsolete, but the principle of the rotating magnetic field will remain a vital, living thing for all time to come.
Mars does not have an atmosphere and does not have a magnetic field today, so the planet doesn't have the protection from radiation that our atmosphere and magnetic fields provide us on Earth.
When the contrary magnetic poles were on the same side, there was an effect produced on the polarized ray, and thus magnetic force and light were proved to have relation to each other.
It is just as foolish to complain that people are selfish and treacherous as it is to complain that the magnetic field does not increase unless the electric field has a curl. Both are laws of nature.
I like to call it the scalar boson because this reflects an essential component of the theory - it means that the field the boson travels through has no preferred direction, unlike the way a magnetic field does.
The magnetic cleavage of the spectral lines is dependent on the size of the charge of the electron, or, more accurately, on the ratio between the mass and the charge of the electron.
Magnetic lines of force convey a far better and purer idea than the phrase magnetic current or magnetic flood: it avoids the assumption of a current or of two currents and also of fluids or a fluid, yet conveys a full and useful pictorial idea to the mind.
Whatever is in your magnetic field is attracting to itself, and so the more love in your field, the more power you have to attract the things you love.
I felt I had dissolved into a pure energy state and become one with the magnetic field surrounding the earth
Saturn itself is a giant planet, and there's much to be gained by investigating its meteorology and studying its magnetic field.
The Christian stands, not under the dictatorship of a legalistic 'you ought,' but in the magnetic field of Christian Freedom, under the empowering of the 'You may.'
I didn't say a pulsed electro-magnetic field cures cancer. I don't believe it does. All I said is that it will help tackle cancer.
The Sun's magnetic field reverses every 11 years. There have been a quarter of a million reversals since our predecessor, Homo Habilis, emerged, and they haven't killed us yet.
