3) the strip is of magnetical material, it holds information about the owner of the card. the information is coded as north poles up or northpoles down areas on the strip.

Answer 2

The fridge magnet question is best answered by the link below.

Magnetic therapy is a very controversial method for pain relief and sometimes healing. It involves wearing things like permanently magnitized bracelets and straps.

The strip on the back of credit cards are special magnets that have indentations that store personal information. When pulled through a card reader, it is actually being pulled through an electric field creating electromagnetic waves which the machine then processes.

Answer 3

Fridge magnets do have poles, it's just the way the magnet was made that it seems that they do not have poles. Try to hold two, together, and you'll quickly discover that they do indeed have poles. I agree with one of the other respondents, magnetic therapy is a lot of hocus-pocus, made for the ignorant to waste their money on.
That magnetic strip on the credit card is just like the magnetic tape used in cassette tapes that you might not now be familiar with. It hold information about you, and your account by virtue of magnetizing tiny pieces of iron, or iron ferrite in certain patterns within the body of the tape.

Answer 4

Fridge magnets are "safety magnets", in that they have lots of small bar-magnet-like strips that go n-s-n-s-n-s (along one edge) to reduce its magnetic field while still making it useful.

The rest of the questions I cannot give you a 100% certain answer on, so I won't waste you time further. :)
