Electromagnetic field - Wikipedia

The field can be viewed as the combination of an electric field and a magnetic field. The electric field is produced by stationary charges, and the magnetic field by moving charges (currents); these two are often described as the sources of the field. The way in which charges and currents interact with the electromagnetic field...

Electric & Magnetic Fields

Electric and magnetic fields (EMFs) are invisible areas of energy, often referred to as radiation , that are associated with the use of electrical power and various forms of natural and man-made lighting. EMFs are typically characterized by wavelength or frequency into one of two radioactive categories: Non-ionizing: low-level...

So then you get moving electrons and all of a sudden you have a "magnetic" field. But at the same time if you take a magnetic dipole ( a magnet as we know it) and move it around you will all of sudden get an electric field. It was a great step forward in the history of physics when these two observations were combined in one...
