Description

Multifunctional Electromagnetic Pulse Experimenter technical field The invention relates to an electromagnetic experiment instrument, in particular to a multifunctional electromagnetic pulse experiment instrument. Background technique In the process of college physics teaching, some high-voltage electrostatic experiments are usually done to deepen students' understanding and memory of the theory. The known high-voltage electrostatic experimental device usually consists of a high-voltage generator, which converts the 220-volt AC mains into a constant high-voltage direct current of tens of thousands of volts, and then leads the high-voltage direct current, and then cooperates with some accessories outside the high-voltage electrostatic generator. Place for high-voltage electrostatic experiments. For example, a Chinese patent (Patent No. 03243505.3, authorized announcement number CN2619407Y) titled "A Small Static High-Voltage Power Supply and Testing Device" of Liaoning Pet...

AI Technical Summary

Problems solved by technology

Known high-voltage electrostatic experiment device has following some defectives: 1, function is single and can only do the experiment of static static phenomenon; There are high requirements for the power output part of the high-voltage power supply and the performance of the regulated power supply; 3. The output DC high voltage cannot be greatly adjusted, which limits the expansion of the experimental content or experimental items; 4. When doing experiments, use the earth As the ground wire, it is neither safe nor convenient

Biophysics is a subject with great development prospects. One of its important research fields is to use electric or magnetic physical quantities to act on biological tissues or organisms to study their production increase, epidemic prevention, disease treatment, high-quality improvement of breeding, etc. Aspect data, this just needs a kind of electromagnetic pulse experimental instrument, but there is no known such experimental instrument at present
