Electric and magnetic fields (EMFs) are areas of energy that surround electrical devices. Power lines, electrical wiring, and appliances produce EMFs. Some people worry about EMF exposure and cancer. A few studies found a link between EMF exposure and a higher risk of childhood leukemia, but the link is weak. Other studies didn't find a link between EMF exposure and other childhood cancers.
For adults, studies of EMF exposure from power lines and electric blankets show little evidence of a link to cancer. In adults, EMFs may reduce heart rate and interfere with brain electrical activity during sleep. This may or may not affect your health.
Some people worry that wireless and cellular phones cause cancer. They give off radio-frequency energy (RF), a form of electromagnetic radiation. Scientists need to do more research on this before they can say for sure.

In the physics of electromagnetism, ''the'' '''electromagnetic field''' is a field composed of two related vectorial fields —the electric field and the magnetic field. When referred to as "the" electromagnetic field, encompassing all of space, whereas typically such a field is limited to a local area, based around an object in space. This means that the vector (spatial)s ('''E''' and '''B''') that characterize the field each have a value defined at each point of space and time. If only '''E''', the electric field, is nonzero and is constant in time, the field is said to be an electrostatic field. '''E''' and '''B''' are linked by Maxwell's equations. Electromagnetic fields can be explained with a quantum basis by quantum electrodynamics.
