Abstract

See full text

A portable electronic PEMF apparatus comprises a PEMF coil, power supply, and electronic switching means contained therein. The power supply along with the switching means provide periodic electric power to the PEMF coil. The PEME coil comprises multiple turns of a conductive wire around a core with an elongated cross section. The core comprises a magnetic shield layer of materials such as mu metal or soft iron. The power supply comprises a battery, a regulated voltage source and unregulated voltage source from the battery and electronic switching circuit, powered by the regulated voltage, for electrically connecting the unregulated voltage source to the coil. The electronic switching circuit is tuned to periodically provide power to the coil at a frequency to generate a non-inverting, varying electromagnetic field from the coil.
