Biological effects of power frequency electric and magnetic fields [PDF]
IEEE Engineering in Medicine and Biology Magazine, 1989 The Institute of Electrical and Electronics Engineers (IEEE) has made an analysis of six recent major scientific committee reports dealing with the biological effects of exposure to electric and magnetic fields associated with electric power distribution and utilization. The conclusions drawn from these committee reports are presented in this summary.

Electric and magnetic fields at power frequencies
Chronic Diseases and Injuries in Canada, 2010 Exposures to electric and magnetic fields are among the most ubiquitous exposures that the Canadian population experiences. Sources of electric and magnetic field exposures may be occupational or residential and include proximity to certain types of electrical equipment, transmission and distribution power lines as well as appliance use.

Effects of Electro-Magnetic Properties of Obstacles in Magnetic Resonant Wireless Power Transfer
Energies, 2021 Magnetic resonant wireless power transmission (MRWPT) is a method of transmitting power over a long distance at a specific frequency. Because this system uses an alternating magnetic field, if an object with electrical/magnetic properties is placed ...

A two-buncher high-efficiency transit-time oscillator with a low guiding magnetic field
AIP Advances, 2021 The energy consumption of high-power microwave sources has attracted much attention in the research field of high-power microwaves. One way of decreasing the energy consumption is to reduce the guiding magnetic field.
