# Electromagnetic field

An electric field is created by an electric charge, and a magnetic field is created when an electric current flows. These two fields together are known as the electromagnetic field.

The electromagnetic field is responsible for the force that we experience when we interact with electricity and magnetism. It is also responsible for the propagation of electromagnetic waves, such as light.

### How does the electromagnetic field work?

The electromagnetic field (EMF) is a physical field produced by electrically charged objects. It affects the behavior of charged objects in the vicinity of the field. The electromagnetic field extends indefinitely throughout space and describes the electromagnetic interaction.

It is one of the four fundamental forces of nature (the others are gravity, the strong nuclear force, and the weak nuclear force). The electromagnetic force is responsible for the electromagnetic radiation that makes radio, television, and X-rays possible, and it is also responsible for the force that holds atoms and molecules together.

The electromagnetic field is produced by a moving electric charge. The strength of the field is proportional to the charge and to the velocity of the charge. The direction of the field is perpendicular to the velocity of the charge and also perpendicular to the plane of the charge's motion.

The strength of the electromagnetic field decreases with distance from the charge. The field also has a magnetic component, which is perpendicular to the electric field and also perpendicular to the direction of the charge's motion.

The magnetic field of a moving charge is responsible for the force that we experience when we hold a magnet near a piece of iron. The force is perpendicular to both the direction of the magnet and the direction of the iron.

The strength of the magnetic field decreases with distance from the charge. The direction of the magnetic field is given by the right-hand rule: if you point your thumb in the direction of the charge's motion and Do humans have an electromagnetic field? Yes, humans have an electromagnetic field. The human body is composed of electrically charged particles, and thus generates an electromagnetic field. This field can be measured using sensitive equipment, and is used in a variety of medical applications such as MRI and EEG.

#### How does EMF affect the body?

As the electricity sector moves towards a more distributed and digital system – the so-called ‘smart grid’ – the role of electromagnetism in our lives is likely to become even more important. With new technologies come new risks, and there is a growing body of scientific evidence linking exposure to electromagnetic fields (EMFs) with a range of health problems.

There are two main types of EMF that we are exposed to:

1. Extremely low frequency (ELF) EMF – this is the type of EMF emitted by power lines, electrical appliances and some types of industrial equipment.

2. Radiofrequency (RF) EMF – this is the type of EMF emitted by mobile phones, Wi-Fi routers and other wireless devices.

Both ELF and RF EMF can penetrate the human body and have been shown to cause a range of adverse health effects, including:

- Cancer

- Neurological problems

- Reproductive problems

- Cardiovascular problems

- Immune system dysfunction

- Disruption of the blood-brain barrier

There are a number of mechanisms by which EMF could cause these health effects. For example, ELF EMF has been shown to disrupt the production of melatonin – a hormone that helps to regulate sleep and the body’s natural circadian rhythms. RF EMF has been shown to cause DNA damage and to promote the growth of cancerous

### How do I block EMF in my house?

There are a few ways to block EMF in your house:

1. Use EMF shielding paint or fabric: This can be applied to walls, ceilings, or floors in order to create a barrier against EMF radiation.

2. Install EMF shielding window film: This type of film can be applied to windows in order to reduce EMF radiation coming from outside.

3. Use an EMF protection device: There are a variety of devices available that claim to protect against EMF radiation, such as pendants, bracelets, and mats.

4. Limit your exposure to EMF sources: This includes avoiding using WiFi and Bluetooth when not necessary, unplugging cords when not in use, and keeping electronics away from your bed at night.
