because old 2p coins are made out of bronze. Bronze is made out of tin and copper, these metals aren't magnetic. However, new 2p coins just look like they are made out of copper, however they only have a coating of copper on them, but the inside is steel, this is called copper plated steel. They are magnetic because steel is magnetic and makes up the majority of the coin.
Old coins may contain iron or steel components, which can make them slightly magnetic. Coins made of metals like nickel or steel can exhibit magnetic properties due to their composition. Magnetic attraction to old coins is a result of the metal content within the coins.
What country are you talking about? New U.S. cents are not magnetic; they're made of copper-plated zinc. The only magnetic U.S. cents were the steel ones minted during 1943 so copper could be used in ammunition. New Canadian cents and British pennies are magnetic because they're made of copper-plated steel. The price of copper went up so much that it cost more than a penny to mint the coins, so the governments were losing money on each one. They switched to steel as a cheaper alternative.
New windmills typically have larger blades and more advanced technology, allowing them to catch more wind compared to old windmills. The larger blades and improved design of new windmills enable them to generate more electricity efficiently.
Paleomagnetic dating utilizes records of "how things were" in a given area across time in the past as a basis for comparison to an unknown sample in order to date it. A link is provided to the Wikipedia article on paleomagnetism, which is the basis for paleomagnetic dating.
The new pennies have less mass because they are now mostly made of zinc with a thin copper coating, while the old pennies were made of bronze. The change was made to reduce production costs and to make the coins more affordable to produce.

The coins to save are the old ones, from before 1965, they were made of silver.
Old ones are old, and new ones are 13.
you can get old ones in a new game but not new ones in a old game
Old ones are old, and new ones are 13.
A lot of people say that the old ones are better, but I personally like the new ones.
new ones because they have more abilities and qualities and features than old ones:)
No British coin is magnetic. Actually, older (1971-1991) 2p coins are not attracted to a magnet and newer ones are. The reason is that the rising price of copper forced the Royal Mint to change the composition from bronze to copper-plated steel. Many other countries that had low denomination copper or bronze coins also changed their compositions during that same time period or, dispensed with the coin coin altogether.
Yes, but as of 04/2010 not many have been released. Demand for coins in early 2010 is down significantly due to the recession, so stocks of old coins are still being distributed and production of new ones is limited so far.
Old cells make new cells so that when the old ones die there are new ones to replace them.
old sponge bob by FAR!!!!!!!!!!!! the new ones suck!!!!! in the old ones, Spongebob was SMART,cute, and yet still goofy! and the old ones made sense!!! in the new ones.. Spongebob and Patrick are SO DARN DUMB!!!!! its crazy!
