EMF
 

Could someone explain to me the difference between a magnetic field and an
electrical field? I am studying for a ham license and I am having difficulty
with these 2 terms.

Thanks

A magnetic field is the field surrounding a magnet.
An electric field is the field produced by a voltage difference.
(Think "Static Electricity" and how it attracts dust.)

A changing magnetic field produces an electric field.
A changing electric field produces a magnetic field.

Electromagnetic radiation (Light, Radio Waves) consists of energy
disturbances that continually switch back and forth between electric and
magnetic fields. (The collapse of the electric field produces a magnetic
field. The collapse of the magnetic field produces an electric field.)

That's about as good as it gets without doing the math.
