What Are DC Electromagnetic Fields?
A Direct Current (DC) electromagnetic field is a type of constant or static field that is generated by either a DC electric field or a DC magnetic field. DC electromagnetic fields have a frequency of 0 Hz, meaning they remain steady over time. These fields can arise from natural sources or from human-made electrical devices and systems.
DC Electromagnetic Fields
DC Electric Fields, can be referred to as an Electrostatic Charge present on an object. This field can be created by rubbing two poorly conducting materials against each other, thus creating a build up of electrons on one of the surfaces. DC electric fields can also exist in the air. Such is the case during a thunderstorm, large-scale electric fields are generated as clouds building up electrical charges, which can lead to lightning strikes. DC electric fields are measured in Volts per meter (V/m). The discharge time in Electrostatic charges, (the time it takes for electrostatic charges to dissipate) can be challenging to measure in open air. Ions are atoms or molecules with a +/- charge. When the environment has too many positive ions, it can lead to a variety of health issues. People can experience reduced serotonin levels due to this, which is associated with depression. In addition, it can cause effects on nerves, glands, and digestion, leading to symptoms such as insomnia, irritability, stress, and a fatigue hyperthyroid-like response.
A balanced ion ratio is ideal—5 positive ions to 4 negative ions. Negative ions are considered beneficial for overall well-being. They can be found in natural environments like waterfalls, forests, and mountains, are generally believed to have beneficial effects on mood and health.
Sources of DC Electric Fields
-
Natural Sources:
- Thunderstorms and Lightning. These electric fields can reach strengths greater than 2,000 V/m.
- Earth’s Surface. The Earth itself generates a natural DC electric field. The Earth's surface is typically negatively charged, and the atmosphere has a positive charge.

DC Magnetic Fields
DC Magnetic Fields can originate from natural or artificial sources. DC or "static" lines of magnetic flux naturally emanate from the earth and provide a compass with the ability to indicate "Magnetic North". DC magnetic fields can also be created from a DC power source of electricity such as battery power, solar power and wind power. DC magnetic fields can be altered by iron ore deposits, and underground streams. DC magnetic fields are measured in milliGauss mG with a DC gaussmeter. Its field strength is dependent on a number of things.
For example, the intensity of direct current, distance from the field source, the type of magnetic metal being used, and the position of the earth. DC magnetic fields can cause geopathic stress on the body, examples include persistent insomnia, daytime exhaustion, interrupted sleep patterns, disruption of enzyme functions, hormonal imbalance, and acceleration of malignant cell growth.
