No. "Magnetic" means that a piece of metal is itself magnetized, so coins are never magnetic. However metals like steel and nickel are attracted to a magnet. But in the case of US Coins, most of them contain a high enough concentration of other metals (copper today, silver in the past) that they're not attracted to a magnet.
The only exception to this were the famous 1943 1-cent coins that were made from steel because copper was needed for the war effort.
There is no scientific evidence to support the claim that magnets can magnetize water. Magnets can interact with water molecules, but they do not magnetize or make water magnetic.
Yes, you can magnetize an iron nail by stroking it with a magnet. This process aligns the magnetic domains within the nail, causing it to acquire magnetic properties. To effectively magnetize the nail, you should stroke it in one direction only, rather than back and forth, to ensure proper alignment of the domains. Once magnetized, the nail can attract small ferromagnetic objects.
You can magnetize a dress making pin by stroking it in one direction with a permanent magnet. I have done it using a good quality fridge magnet. Dress making pins may become magnetized when they are dropped on a hard surface, for example a tiled floor.

Two north poles will repel each other due to their like magnetic charges. To "magnetize" them together, you would need to flip one of them around so that it becomes a south pole. This will create attraction between the two poles and they will come together due to the magnetic force.
Copper is not a magnetic material and does not magnetize easily.
The US Mint produces circulating coins, commemorative coins, and bullion coins for the United States.
You can magnetize a paper clip by passing it repeatedly over a large magnet.
No, most US coins are not magnetic.

No, retailers are allowed to accept whatever in payment for goods, be that US coins, Chinese Coins, gold and silver coins, or toothbrushes. A retailer can refuse to honor some or all US coins. However, since US coins are legal tender, a company cannot sue you for not paying a bill previously agreed upon in US dollars for paying in US coins. But at the point of purchase, a retailer can demand payment in whatever and can refuse US coins.
