MSH: Fields representing the joint interplay of electric and magnetic forces.,NCI: Field of force associated with a moving electric charge and consisting of electric and magnetic fields that are generated at right angles to each other.,MEDLINEPLUS: <p>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. </p><p>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.</p><p>Some people worry that wireless and cellular phones cause cancer. They give off radio-frequency energy (RF), a
