This video shows how I build a ZVS driver to power a small induction heater than can make pieces of metal weighing ~1 gram or less glow red hot. The circuit takes in 10-16V and the final variant shown in this video oscillates at about 160 kHz. I also show how this circuit can be used to drive a flyback transformer. This is a very modestly powered circuit, but the advantage of a ZVS driver is that it can be scaled up to tens of kW without much of a problem. The voltage on the coil (and the MOSFET V-DS) is about 3 times the input voltage, so to use higher voltages of say, 36 or 48V, I would need MOSFETs rated for a higher V-DS like an IRF250 or IRF460. NOTE: My statement about inductance not changing is inaccurate. Inserting a ferromagnetic object into the coil *does- increase the inductance and reduce the frequency.

This video shows how to make a plasma tube out of a glass bottle and a high voltage supply that takes advantage of Paschen's law (https://en.wikipedia.org/wiki/Paschen%27s_law) to generate a long electrical arc from the reduced breakdown voltage of air in a low-pressure environment. The bottle runs at about 0.1 atmospheres, so this would be considered a very low vacuum, but it's more than sufficient to demonstrate the relationship between breakdown voltage and pressure. A dedicated vacuum pump could evacuate this bottle down to a few thousandths of an atmosphere, and the same size arc could be generated with a few hundred volts instead of 30,000 volts. -Diamond hole bits used in the video: https://www.amazon.com/gp/product/B01L92YM1A/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1 Music: Serge Pavkin - Technology For Life https://www.youtube.com/watch?v=caIqdAb5w7o&list=PLGR5IhV9jJZHLLkv-EeVNCKogv8Hb9L6O&index=90 Serge Pavkin - Intergalactic https://www.youtube.com/watch?v=0Z0vPtMEvVg&list=PLGR5IhV9jJZHLLkv-EeVNCKogv8Hb9L6O&index=142 https://rumblevideoarchive.wordpress.com/

A bipolar tesla coil is simply a tesla coil that has both sides of its secondary coil connected to electrodes facing each other, as opposed to a typical tesla coil which uses earth ground (or a sufficiently large ground plane) as one pole of its secondary coil. This is probably the cheapest, easiest, and most convenient way to create a very high voltage power supply - simply a dimmer switch and an ignition coil. The output of my supply is over 30,000V DC.

In this video I'm going to use a pulse of current from a 1,200 volt capacitor bank to launch metal objects through electromagnetic induction. This is a really interesting area of electromagnetism, because it's effectively generating a huge repulsive magnetic force between two objects without any magnets actually being involved. The large electromagnet used in the second part of the video is from a microwave transformer. The core can be sliced fairly easily with an angle grinder if you make your cuts right at the weld lines. As a transformer, magnetic flux is circulated between the primary and secondary windings, but with one end open, magnetic flux is free to "leak" out into space, turning the transformer into an electromagnet. This is probably the cheapest and easiest way to make a very powerful electromagnet.

In this video I experiment with different improvements to electromagnet coils and build a test fixture to measure my results and compare them to magnetic finite element simulations. Ultimately, i measured an efficiency increase of 51% on a coil that was covered in a shell of ferrous material acting as a magnetic flux guide.

The vastly-improved second version of my tiny 2-volt hand cranked generator (https://www.youtube.com/watch?v=0PiGNDu3Oqs). This generator puts out up to 32 volts open-circuit and ~500 mW at optimum load, and can charge a phone/tablet. It's built from a pair of 60mm speaker magnets for the rotor and four 5,000-turn coils of 32 gauge wire. To get the fast rotation of the magnets, i use a 1:10 gear ratio.

In this video i show how to use an electromagnet with an optical sensor to continuously accelerate ferromagnetic / magnetic spheres around a circular track. A 12V LiPo battery supplies power to a driver board that energizes a 300-turn coil when a sphere approaches, causing it to accelerate into the center of the coil. I've successfully run the device with up to 3 spheres at a time. The electromagnet is far more powerful against a magnetic sphere, but much more erratic and unpredictable, and the sphere tends to stop suddenly after a few rotations.

It uses (3) A1309 sensors to read up to +/- 220 Gauss on 3 axes, and (1) A1308 sensor to read up to 1500 Gauss. One Gauss is 1/10,000 Tesla - which is the SI unit for magnetic field strength. NOTE: The part numbers shown in the schematic are reversed. A1309/A1308 are swapped.
