The glass envelope of discharge tubes and the older type of gas-filled X-ray tubes fluoresces with a greenish-yellow glow in those regions subject to cathode-ray (electron) bombardment. In Fig. 8.1 a dashed line represents the image potential (cf. Though all current-carrying conductors produce magnetic fields, an electromagnet is usually constructed in such a way as to maximize the strength of the magnetic field it produces for a special purpose.

Increase either or both of these and you get a more powerful electromagnet. Gaseous Dielectrics. — The discussion of the preceding chapters has been largely concerned with the limiting ideal cases of materials that were either perfect conductors in which no electric field could exist or perfect insulators in which there was no net motion of charge. This must equal the electrical work done, which is the product of the charge per mole and the potential difference between the solution and electrode; hence V RT. ~F7 log < (!) where v is the charge per ion or valence and V is the electrode potential.
