A PEMF unit is a Pulsed ElectroMagnetic Field device. It is a device that delivers a magnetic pulse to the material or body that the pulse is directed at. There are hundreds of web links that have explanations of the theory along with videos and demonstration on how this technology works. Please consider researching PEMF on the Internet for additional information.
The Bob Beck Style of a PEMF device typically uses a coil that, when energized by a capacitor and discharged through a SCR, will deliver a magnetic pulse that is extremely strong. The circuit diagram of this particular unit will generate 60 Amps or better, and a 100 volt pulse for 1 to 3 milliseconds. It will easily peg a Trifield 100XE magnetic field strength meter at 2 feet or better when used in conjunction with an AURORASKY multipurpose MAG Coil. (Please see Bifilar MAG Coil project for coil detail and more info.)
The NEW PEMF has a control pentiometer. The pulse frequency can be varied from roughly 1 Hz to 15 Hz. This will enable pulse settings to the 4 Hz binaural and 7.83 Hz Schumann Resonance frequencies. Precision frequency adjustment can be made by using the Spooky2 as a frequency meter. (See below reference PDF and video on how to do this.)
An explanation of why a light bulb is in order. This PEMF device uses anywhere from a 25 to 100 watt incandescent light bulbs as a current limiting resistors. These bulbs can be found in a ‘DOLLAR Store’ or equivalent for a typical price of 50 cents each. An incandescent light bulb has a variable resistance. For a 60 watt bulb the cold resistance is typically 20 ohms. The bulb’s hot resistance is typically 100 ohms. To provide a variable current limiting resistor capable of handling 600 watts or better can cost $20 and complicate the circuit design immensely. It should become apparent that it is a matter of economics to use a light bulb verse the alternative. For aesthetics and to prevent a light flashing annoyance, the bulbs are painted with black heat resistance barbecue paint.
It is suggested that a simple Home Depot AC timer, or equivalent, be used to insure the coil is protected from excessive heat by running it for extended periods of time. Magnetic therapy sessions typically run less than 30 minutes. The magnet wire used in the MAG Coil is rated at 150 degrees centigrade. However the plastic spindle used for the wire wrap is unfortunately rated at a much lower temperature. Running a MAG Coil for 1 hour actually deformed the spindle during a performed endurance test. Be warned there is a lot of energy being generated by this PEMF device and excessive run times are to be avoided. Let the coil cool down between sessions. Use a sock or towel to handle the coil when running the PEMF at maximum energy levels.
The PEMF has an internal switch which disables two of the charging capacitors. The bottom cover actually has to be removed when changing the setting of this switch. Be very careful to touch only the switch inside the box because the capacitors will most likely have a stored charge on them. The charge will make you jump, if touched! When using the MAG Coil with this device, 3 charging capacitors are more than enough to do the job. The switch is provided for larger coils. There has already been one user running a much larger coil with this PEMF. Between using different bulb wattages and the internal switch, this PEMF becomes a versatile tool for running other 3rd party products. eg Mats, Larger Coils, and specialty PEMF delivery devices. PEMF fabrication cost is $75. Use the ’Contact Button’ for more
