Do automobile alternators always produce electricity when the engine is on?

Yes, the alternators job is recharge the battery after it starts the engine as well as operate the engine electronics, lights, radio a/c and heater and all other electrical items
the alternators output will vary with engine rpm and load. but the output is limited by the voltage regulator which will maintain 14.5 max with the amperage rating at whatever the alternators rated for. Example, at an engine idle of around 750 rpms the alternator will produce around 12.5 volts and around 30amps. when the engines running at acceleration or crusing speed of 2500 rpms the alternator will produce 14 volts and 60 amps. these numbers will fluxuate along with the demand and load.
if you turn everything electric on the load of course goes up so the alternator produces more power to keep from draining the battery. such as if no electric items are on the alternator will produce a lower number just enough to keep everything going w/o using the battery..
hope this helps

How do 1 wire alternators work?
A one wire alternator has one wire that sends electricity to the battery and electrical system. They usually always have an internal regulator.

How electricity produce magnets?
An electric current will always be surrounded by a magnetic field. The reason for the relationship is not exactly obvious; it has been explained by Albert Einstein in his paper "On the electrodynamics of moving bodies".
When is nuclear energy going to be used as an everyday energy?
You clearly don't understand how electricity is distributed. At present in the US nuclear power electricity is about 20 percent of the total used. This means that just about everybody uses some nuclear every day as part of their use of electricity. Nuclear power is always going to be used to produce electricity, you won't ever have one in your basement.
Does electricity always produce a magnetic force?
Magnetism, an aspect of electromagnetism, one of the fundamental forces of nature. Objects such as a bar magnet can influence other magnetic materials, without physically connecting them, because magnetic objects produce a magnetic field. Magnetic fields are usually represented by magnetic flux lines. Magnetic fields influence magnetic materials and also influence charged particles that move through the magnetic field.
How much does electricity way?
Electricity has no weight. It's made of electrons that were always there anyway.
