What’s an Electromagnetic Field?

Learning about electromagnetic fields can be a little discouraging at times. Some definitions of electromagnetic field, or EMF, basically tell you that an electromagnetic field is a field of electromagnetic energy. This isn’t really helpful, and it doesn’t give you a better understanding of EMFs. Here are some answers to common questions about electromagnetic fields and PEMF therapy.

What is an electromagnetic field?

If you want a textbook definition, an electromagnetic field refers to the space or area of electromagnetic energy that surrounds an object. Here’s the Merriam-Webster definition of electromagnetic field:

a field (as around a working computer or a transmitting high-voltage power line) that is made up of associated electric and magnetic components, that results from the motion of an electric charge, and that possesses a definite amount of electromagnetic energy

In other words, EMFs are energy, and lots of things – both natural and man-made – produce electromagnetic fields. The closer you get to the source of the field, the stronger the field will be.

Are EMFs dangerous?

Televisions, microwaves, power lines, computers, cell phones, wireless routers, the earth, thunderstorms, and even people produce electromagnetic energy. Some EMFs are dangerous, but not all electromagnetic fields are dangerous.

It all depends on the frequency. The process of electromagnetic energy moving away from its source is known as electromagnetic radiation. There are harmful levels of radiation, known as ionizing radiation, and non-harmful levels known as non-ionizing radiation.

So are the EMFs in PEMF therapy safe?

Non-ionizing radiation does not carry enough energy to remove electrons from molecules or atoms. Of course, we know that this does not mean that all non-ionizing radiation is completely harmless. UV radiation from the sun, for example, is technically non-ionizing, bur it can damage our cells after prolonged exposure.

The EMFs used in pulsed electromagnetic field radiation, however, are extremely low frequency. PEMF Complete systems generate electromagnetic fields at a frequency between 50 to 60 Hz, which is slightly higher than a static field. Radio waves produce EMFs at frequencies over 100 kHz, or  100,000 Hz.

So, yes. The EMFs in PEMF therapy are completely safe.

If EMFs are everywhere, how does PEMF therapy work?

If EMFs are so common, and the earth even produces a constant electromagnetic field, why would PEMF therapy have any affect at all?

The frequency of PEMF therapy is very low. Lower than the phone you constantly keep in your pocket and lower than the WiFi you use everyday.

PEMF coils allow you to target the EMFs during PEMF therapy. Unlike ambient electromagnetic energy, this lets you focus on specific problem areas.

The biggest difference with the EMFs in PEMF therapy and other EMFs is the pulsation. During PEMF therapy the electromagnetic fields are generated in waves or pulses rather than a constant field. This is what stimulates the cells, improving function, cellular health and cellular regeneration.
