what is on the nails is ltlle partials and the banging nocks the particle off
By banging a nail it causes all the tiny domains to face different directions so you end up with a non-magnetised nail.
A Weakly magnetised nail will pick up less paper clips then a highly magnetised nail, Hope That Helps:)
The strong magnetised nail will pick up more paper clips than the weak magnetised nail.That is because the strong magnetised nail is getting more strength and that means that the weak magnetised nail is getting less strength.in a steel nail there are these things called domains, in a weakly magnetised nail some of them will be pointing north, south, east and west, but however in a strongly magnetised nail all the domains will point to north.
When you bang the nail the domains in the material you are banging jumble up to face different ways so the material is no longer a magnet!!
what is the diffrence between a magnetised nail and a unmagnetised nail
banging the magnet makes the 'mini-magnets' inside the big magnet go back to the way they were before magnetism. xx
Because the domains get muddled up and eventually return to a random order.
The nail gun was created because banging thousands of 3" nails in with a hammer was very slow.
Yes, every material has its limit in this respect.
Like poles will repel.Unlike poles will attract.
The magnet induced magnetic properties in the nail and the paper clip, causing them to attract each other. When the magnet was removed, the induced magnetism in the nail and paper clip allowed them to remain attracted to each other.
Graphics can't be shown on Answers.com. Take a large iron nail (or several nails, 6 inches long). Wrap several layers of thinly insulated wire round the nail(s), and connect the bared ends of the wire to the positive and negative terminals of a 9 volt battery. As the electrical current is sent through the coiled wire, the iron nail(s) becomes electro-magnetised and will attract metal. Turn the current off, and the metal will drop off, for the nail(s) are no longer magnetised.
