A magnetic field is a field explaining the magnetic influence on an object in space. A electric field is a field defined by the magnitude of the electric force at any given point in space.
Read moreIs a magnetic field an electric field?
A magnetic field is not just an electric field with relativity applied , i.e. an electric field viewed from the wrong reference frame. In reality, a magnetic field is a fundamental field which can exist in a certain reference frame without needing any help from an electric field.
Read moreWhat is causes of low-frequency in electricity?
The main source of extremely low frequencies is alternating current carried in power lines, wiring and household appliances . The electromagnetic field generated has the same frequency as the current that causes it, i.e.50Hz or 60Hz (the latter predominantly in US).
Read moreAre EMF waves harmful to humans?
Despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health . The focus of international research is the investigation of possible links between cancer and electromagnetic fields, at power line and radiofrequencies.
Read moreWhich type of waves are toxic to humans?
The most dangerous frequencies of electromagnetic energy are X-rays, gamma rays, ultraviolet light and microwaves . X-rays, gamma rays and UV light can damage living tissues, and microwaves can cook them.
Read moreWhat is ELF magnetic field?
Extremely low frequency (ELF) fields includes alternating current (AC) fields and other electromagnetic, non-ionizing radiation from 1 Hz to 300 Hz . ELF fields at 60 Hz are produced by power lines, electrical wiring, and electrical equipment.
Read moreWhat is an EMF rating?
EMF is a combination of electrical and magnetic fields . The strength of an EMF is directly related to the amount of electricity in use (the current) and to the electrical potential (the voltage) in the electric circuit. That means the more current or the higher the voltage, the greater the EMF which could be generated.
