Can a permanent magnet be coiled to also double as a electromagnet? Could the current reverse or double the poles? The wire coil is made from a long thin magnetic bar.

Yes.
Also you can coil wire around a nail to make an electromagnet and if the current is kept on for a sufficient time then the nail becomes noticeably magnetic. So being used as the core of an electromagnet can make a permanent magnet.

"At the junkyard, an electromagnet holds a 1 ton car freely in the air (no acceleration exc. gravity). Assuming 100% power efficiency, how many Watt electrical power are needed?" - I know that the magnet produces 10,000 N, but in order to get the 𝑊, I'd need some velocity (W = Nm/s), and I don't see any m/s?

Nowadays an unlimited amount of information can be transferred around the planet using wireless methods. Is that possible to transfer the information using natural electromagnetic field such as Earth magnetosphere? What else natural fields are able to carry clusters of information besides artificially generated waves?

(a) A car generator turns at 400 rpm when the engine is idling. Its 300-turn, 5.00 by 8.00 cm rectangular coil rotates in an adjustable magnetic field so that it can produce sufficient voltage even at low rpms. What is the field strength needed to produce a 24.0 V peak emf? (b) Discuss how this required field strength compares to those available in permanent and electromagnets.

Is there anyway to transfer the electromagnetic energy of a naturally occurring magnet into usable electricity kinda like using the magnet as a battery?

If I bring a magnet close to a copper bar, there will be no attractive or repulsive force. Similarly, if I bring a magnet close to a copper electromagnet, still there is no attractive or repulsive force.
So can't we say that the magnetism of regular copper and a copper electromagnet the same ?
If no, then why? What difference is there between regular copper and a copper electromagnet? How does copper get changed if electricity passes through it?

If we isolate wire with thin wire and assuming that no heat rejected by wire then does electromagnet work. If it work then it violate conservation of energy.
