Several different electrical, magnetic or electromagnetic physical phenomena can be used to transmit signals over a distance without intervening wires.

His book De Magnete quickly became the standard work throughout Europe on electrical and magnetic phenomena.

They were intended to observe various radiation and magnetic phenomena in the ionosphere and beyond.

Another oft-cited example is Maxwell's equations, derived to model the elementary electrical and magnetic phenomena known as of the mid 19th century.

Overall, Kohlrausch was involved in the measurement of electrical, magnetic and electrochemical phenomena for almost 50 years.

It is believed at the present time that all so-called magnetic phenomena result from forces between electric charges in motion.

As an aside, some of the most interesting magnetic phenomena to see can be found in magnetic liquids.

In the late 16th century William Gilbert set out to describe the behavior of magnetic and electrostatic phenomena.

Experimentally, there are many techniques that exist to study magnetic phenomena, each with its own limitations and advantages.

In the absence of magnetic phenomena, the strength of this current is indicative for local electronic properties.
