Elektromagnet 3T
Ahoj, je vůbec možné spíchnout takovýto elektromagnet na železným hranolu průřezu 25x25mm ohnutým do tvaru C aby v tý mezeře (13mm) bylo 3 T?

Musel byste mít 2 cívky, každou z jedné strany mezery těsně u ní. Vzhledem k velikosti té mezery a uspořádání cívek je pak Fe jádro už docela problematické. Jedna cívka na běžném jádře neposlouží, protože FE jádro indukci 3T není schopno do mezery nasměrovat. Možná jádro s proměnným průřezem, kdy velký průřez je pro tok okolo cívek a malý pro tok uvnitř cívek. To jádro je nakresleno v průřezu, ideálně by obklopovalo cívky dokola.

Testuji toto viz.obrázek ...blbý na tom všem je, že tam je napsáno jen elektromagnet a nic víc, nemám představu o materiálech. Tedy já tam nemám přesně železo ale nějakou nízkouhlíkovou ocel.
Popis k tomu obrázku od N. Tesly:
One of the changes is that the adjustable knobs A and B (Fig. 4), of the discharger are held in jaws of brass, J J, by spring pressure, this allowing of turning them successively into different positions, and so doing away with the tedious process of frequent polishing up.
The other change consists in the to_nic of a strong electromagnet N S, which is placed with its axis at right angles to the line joining the knobs A and B, and produces a strong magnetic field between them. The pole pieces of the magnet are movable and properly formed so as to protrude between the brass knobs, in order to make the field as intense as possible; but to prevent the discharge from jumping to the magnet the pole pieces are protected by a layer of mica, M M, of sufficient thickness, sl sl and s2 s2 are screws for fastening the wires. On each side one of the screws is for large and the other for small wires. L L are screws for fixing in position the rods R R, which support the knobs.
In another arrangement with the magnet I take the discharge between the rounded pole pieces themselves, which in such case are insulated and preferably provided with polished brass caps.
The to_nic of an intense magnetic field is of advantage principally when the induction coil or transformer which charges the condenser is operated by currents of very low frequency. In such a case the number of the fundamental discharges between the knobs may be so small as to render the currents produced in the secondary unsuitable for many experiments. The intense magnetic field then serves to blow out the arc between the knobs as soon as it is formed, and the fundamental discharges occur in quicker succession.
Instead of the magnet, a draught or blast of air may be to_nic with some advantage. In this case the arc is preferably established between the knobs A B, in Fig. 2 (the knobs a b being generally joined, or entirely done away with), as in this disposition the arc is long and unsteady, and is easily affected by the draught.
Ta věta: The intense magnetic field then serves to blow out the arc between the knobs as soon as it is formed, and the fundamental discharges occur in quicker succession.
Co mám chápat tím "fundamental discharges"? Tesla to používal v primáru TC, jestli má být onen "základní nebo podstatný výboj" vlastně vybitím či jinak řečeno přelitím náboje z kondenzátoru do primární cívky a to ostatní je vlastně jen pendlování náboje z cívky zpět do kondenzátoru a tak několikrát zasebou je vlastně jen ztrátou energie na teplo v jiskřišti? Jakou účinost přenosu to pak má na případný sekundár pokud ho tam umístíme?.... směšnou nejspíš.
