Anticancer treatment strategies increasingly seek to raise reactive oxygen species (ROS) levels, cause macromolecular damage, and kill cancer cells. Electromagnetic fields can elevate intracellular reactive oxygen species ...
Doctors at Guthrie Healthcare System, in Sayre, Pennsylvania, have documented a case of a teenage boy who swallowed 21 disc magnets. In their paper published in BMJ Case Reports, the medical team describes how they found ...
Artificially causing—or inducing—labor is becoming increasingly common, yet this practice comes with risks and its level of success is difficult to foresee. But now, new research may offer a way to help predict outcomes ...

Magnetic fields surround magnetic materials and electric currents and are detected by the force they exert on other magnetic materials and moving electric charges. The magnetic field, at a given point, is specified by both a direction and a magnitude (or strength); as such it is a vector field.
In special relativity, the electric field and magnetic field are two interrelated aspects of a single object, called the electromagnetic field. A pure electric field in one reference frame is observed as a combination of both an electric field and a magnetic field in a moving reference frame.
