Electronic signal.
What is a electric current that is varied to represent information called?
Electronic signal :-)
What can be done with an electromagnet that cannot be done with a regular permanent magnet?
Its strength can be easily manipulated (e.g. you can switch it off). Or the strength can be varied with the current. Electromagnets can reverse polarity (by reversing the current).
How do waves carry signals?
Waves can be varied (modulated) by either changing amplitude (amplitude modulation AM) or changing frequency (wavelength) (frequency modulation FM). The modulations are used to carry the information signal.
What are the parts of a circuit and their function?
A circuit is any arrangement of objects (circuit elements) in which an electric current flows through a closed loop. The only absolutely essential elements of a circuit are something to make the current go, called a source, and something to carry the current around the circuit, called a conductor (usually, a wire, a metal trace on a circuit board, or some of each.) There are many other kinds of circuit elements that have various properties, and each of these may serve a number of different functions. The most basic of the elements are the resistor, the capacitor, and the inductor. Others include transformers, transistors (of various types.) diodes, and many more. There properties and functions are so varied as to far exceed what can be written here; indeed, they fill large textbooks. Multiple sources exist on the web with some basic information on these that is beyond the scope of a single answer here. Just google it, and try Wikipedia.

Why is the letter i used to identify electric current?
The history of electrical study is a long an varied one. Because of this, many conventions used when describing electrical phenomena seem archaic or just plain weird. This particular oddity, using the letter 'I' to represent an electric current is courtesy of Georg Ohm [1] the father of the famous 'Ohm's Law'. Ohm was describing the relationship between resistance, voltage and the Intensity of the electric current [2]. We get the I from intensity. In retrospect, this is ironically fortunate because it saved us from having to later, choose an 'odd' letter to represent Capacitance. [1] Wikipedia: Georg Ohm http://en.wikipedia.org/wiki/Georg_Ohm [2] IEEE History Center: FAQs http://www.ieee.org/web/aboutus/history_center/bitsbytes/faqs.html The origin of "I" is "intensite", the French word for "current", as Ampere was French.
How long does an electric car run?
Not long enough! and not in enough extreme temperatures for Minnesota's varied climate.
What particles move during an electric circuit?
Neutrons. (In type ax1, ay1 is varied due to voltage and amp conditions.)
Where can one purchase an electric radiator?
The places to purchase electric heaters are many and varied. The best place to start would be Amazon. If you are on a tight budget, a good place to try would be eBay.
What is the voltage of a typical electric cell?
Most cylindrical cells supply 1.2 to 1.5 volts, with a varied level of amperage between sizes.

What nun wears a blue habit?
The varied colors represent the different orders the nuns come from. These can vary so much even by the shade of blue.
What is a device that that produces electric current by rotating a coil of wire in a magnetic field?
A generator or alternator. If the magnetic field is permanent, the current produced from the coil will be alternating current. AC. Alternators usually work the other way round. The magnet is spun inside a coil of wire. The power is taken off from the stator. The rotor is an electromagnet, fed via slip rings on the shaft. The strength of the magnet can be varied and controlled externally, to control the output voltage.
What can be done with an electromagnet that cannot be done with a regular permanent magnet?
Its strength can be easily manipulated (e.g. you can switch it off). Or the strength can be varied with the current. Electromagnets can reverse polarity (by reversing the current).
Where can one purchase used electric towel rails?
