To make magnetic field strong enough I need sufficient current, but insufficient to burn the coil. We use pulses, so the current will not be at full strength all the time. Therefore the windings is able to carry higher current then maximal direct current of the wire without melting the wire. Ideally I would have a superconductor, but let's leave it for the future ;-) So far current of several A will be enough. For that I need modulated current source (with low output impedance). | To make magnetic field strong enough I need sufficient current, but insufficient to burn the coil.

- | This coil has approximately 2 x 30 thread spools with average radius of 17 cm and height if 4 cm. Very imprecise estimate of its induktace L would be around 1H for relative permeability 100, which will maybe have the core of the coil made by reactor's sphere with iron nanoparticles. Wire's cross-section is 0,75mm<sup>2</sup> so maximal current load about 13A. | + | This coil has approximately 2 x 30 thread spools with average radius of 17 cm and height of 4 cm.

- | Prakticky jde téměř o sinusový (kosinusový) průběh s jednou kladnou polaritou a vynechanou zápornou polaritou. Frekvence je v klidu člověka něco kolem 1,2 Hz. | + | Basicaly it is almost sinusoidal (cosine) wave with one positive polarity and missed negative polarity. Fraquency of a calm man is around 1,2 Hz. |
- | Impedance této cívky Rl při výše uvedené frekvenci tedy bude se zanedbáním odporu měděného drátu kolem 2 x 2 Ohm, pokud uvažuji poloviční frekvenci kvůli polovičnímu sinusovému signálu (jen plus napětí). To je srovnatelné s dnešními zvukovými reproduktory. | + | Impedance of this coil Rl, with the above mentioned frequency, will be, if we neglect resistance of copper wire, around 2 x 2Ohm, if we consider half frequency because we have half sinusiodal signal. It is comparable with todays reproductors. |
- | Proud 10 A mi dá při dané impedanci potřebné napájecí napětí 2 x 20 V. To máme příkon 2 x 200 W. To jsou jen odhady a realita se uvidí. | + | Current 10A with above impedance will give us needed voltage 2 x 20V. It gives power 2 x 200W. These are only estimations and reality remains to be seen. |
