The temperature rose steadily as one progressed away from the violet, and reached its high­ est point at the extreme red. Astonished, Herschel won47 Atom dered what would happen if he placed the thermometer bulb beyond the red. He found, to his even greater aston­ ishment, that the temperature rose to a higher figure there than anywhere in the visible spectrum. Herschel thought he had detected heat waves. In a few years, however, the wave theory of light was established and a better interpretation became possible.

Nevertheless, this pull is proportional to the product of the two masses involved, and the Earth and Moon are so massive that the Earth's gravitational pull is still large enough at the distance of the Moon to hold the Moon in orbit.

When this is done, the filings arrange themselves in a group of curved lines ex­ tending from one pole of the magnet to the other. Pere39 Atom grinus had noticed this, and, in 1831, the English scientist Michael Faraday (1791-1867) considered the subject. To Faraday it seemed that the influence of the magnet stretched out through space in all directions in a magnetic field that weakened with distance according to the inverse square law. Through the field one could draw a vast number of lines (magnetic lines of force) that marked out regions where the strength of the magnetic field was the same.
