coz i dont know
because the iron filings are in a magnetic field
The process by which a iron piece touching a permanent magnet behaves as a magnet as long as it maintains contact is called magnetic induction. not only does this work when the iron is physically touching the magnet but it works as long as the piece of iron remains under the influence of the magnet. A iron piece attracted to a magnet through a paper with out any physical contact will also behave as a magnet.
An electromagnet is a piece of iron(usually a cylinder or rectangle)wrapped around with copper wire that when electricity runs through it it works like a magnet. Also called artificial magnet.

Each piece would become a separate magnet with its own two poles, just like the original bar magnet. Cutting a bar magnet does not eliminate its magnetic properties; each piece will still have a north and south pole.
no it wont because copper is not a type of magnet even though it is a metal
A piece of paper is not magnetic, so it does not interact with the magnetic field produced by the magnet. The magnet can only attract materials that are magnetic or contain magnetic elements, like iron or steel.
A magnet won't pick up a penny because pennies are made of non-magnetic materials like copper and zinc, which are not attracted to magnets. Similarly, a magnet won't pick up a piece of wood because wood is also non-magnetic and does not have magnetic properties to be attracted to the magnet.
just act normal talk to him..and just be normal :) any one who doesnt like you for who you are then hes not worth it :)
A magnet is an object that is magnetic if it displays magnetic properties. Think of it like this; If bar magnet attracts a piece of metal towards it, it is using magnetism (fluxuations in electric current) and therefore the magnet can be said to have magnetic properties.
When you touch a piece of iron to a permanent magnet, the iron can become magnetized temporarily because it can align its domains with the magnetic field. However, once the iron is removed from the magnet, it will lose its magnetism over time. The iron itself does not retain a permanent magnetism like the original magnet.
it doesnt sound like its normal
