Properties of the field Faraday’s Law may be stated roughly as ‘a changing magnetic field creates an electric field’. This is the principle behind the electric generator. Ampere’s Law roughly states that ‘a changing electric field creates a magnetic field’.

Facts About the Force

These equations are fundamentals of electromagnetism. Then they cannot be treated independently of each other, because the changing electric field produces a changing magnetic field and the newly produced changing magnetic field produces a changing electric field, which is an electromagnetic wave.

Electromagnetic radiation, is a form of energy emitted by moving charged particles. As it travels through space it behaves like a wave, and has an oscillating electric field component and an oscillating magnetic field. These waves oscillate perpendicularly to and in phase with one another.

The main effect of radiofrequency electromagnetic fields is heating of body tissues. Despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health.

Advantages: It helps detect broken bones. It also helps people in engineering and industry find out if a steel or concrete structure has small cracks that are not visible to humans. Disadvantages: If there is too much exposure to X-rays, it can cause cancer.

Advantages of Electromagnetism It can be turned on and off by cutting of the electrical current. It does minimal harm to the human body because it’s not using x-rays like an x-ray does. It is easy to use and can help is many medical and casual things.

Electromagnetic power sources may not be as useful, or can perhaps be dangerous to use, under certain circumstances. These same electromagnetic fields can also interfere with other electrical and electronic devices, such as cell phones and computers. …

These include nerve regeneration, wound healing, graft behavior, diabetes, and myocardial and cerebral ischemia (heart attack and stroke), among other conditions. Preliminary data even suggest possible benefits in controlling malignancy.

The few recent studies on environmental effects of electromagnetic fields (EMF) have mostly focused on extremely low frequency (ELF) fields, such as those generated by overhead power cables. They mostly considered plants and not species that would be expected to be among the most sensitive to EMF.

Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness”). It can also result in long-term health effects such as cancer and cardiovascular disease.

It was found that children living in homes as far as 600 m from power lines had an elevated risk of leukemia. An increased risk of 69% for leukemia was found for children living within 200 m of power lines while an increased risk of 23% was found for children living within 200 to 600 m of the lines.

In conclusion, there are no known health risks that have been conclusively demonstrated to be caused by living near high-voltage power lines. But science is unable to prove a negative, including whether low-level EMFs are completely risk free.
