It all depends on the way in which the iron's 'domains' are aligned. Iron is inherently magnetic as a material, but can become demagnetized as time goes on, due to sudden impact or when affected by another magnetic source. For iron to become magnetized 'domains' need to be in parallel with each other so the magnetic field created all flows in the same direction. An unmagnetized iron source has all of its domains misaligned A brief explanation of domains are a series of positive and negative charged atomic particles within the iron itself which behaves much like tiny magnets themselves.

Yes, iron is magnetic.
the magnet attracts to iron by the magnetic field both the iron and the magnet have
the substance which has capacity to attract iron particle is known as magnetic object
In a magnetic material that is not a magnet, magnetic domains are arranged in random fashion canceling the net magnetic field. If such a material, like an iron rod, is exposed… to a strong magnetic field, the domains will arrange themselves in the direction of the applied field and hence object will become magnetized.
Hard disks and floppy disks are examples of magnetic media.
1. Build a motor/generator; 2. (This answer would be sick, so I left it out) 3. Create magnetic fields (duh) 4. Ever heard of a game called Polaris? Well,… just mess with magnets, and you could end up making them jump over each other. 5. You could hold a magnet under a table, and place another on top of the table. See what happens when you move the one underneath around. 6. You could put iron fillings in a jar, close the lid, then move the magnet around outside it. (actually, just messing with iron fillings in general is fun) 7. You could grind up cheerios (any cereal works well enough) and move a magnet around in the result. You should have particles stuck to the magnet. This is the iron in the cereal! 8. I hear if you get a strong enough magnet, you can destroy many electronic appliances, including a TV and a computer.

I'm not sure about quarters in particular. I do know that the British 1 and 2 pence coins used to be made of copper, a non-magnetic element. However recently the price o…f copper rose so much that the 1 and 2 pence cions were worth more than 1 or 2p. To remedy the situation the coins are now made of copper-plated steel. Steel is magnetic, hence the coins are. In short I would guess it is because some quarters are made of magnetic metals like steel and nickel whereas other are not.
Ferro magnetic materials (those attracted to magnets) have a special arrangement of their electrons which makes them susceptible to magnetic fields. Materials without this spe…cial electron structure are not affected my magnets or electric fields in the same way.
The magnetic poles of them. The North Poles pull on the South Poles, I think. No one know how these pheonomenon forces are create but they have some properties that we know of… today
1.Stroking it with a magnet 2. Applying a current to a coil of wire wrapped around the iron
Every electron is a tiny electromagnet. A pair of electrons spinning in the same direction makes a stronger electromagnet. A pair of electrons spinning in opposite directions,… however, isn't magnetic. The magnetic fields of each cancel one another. This is why most substances are not magnets. In most atoms the various fields cancel each other because the electrons spin in opposite directions.
Most types of Iron are magnetic, however depending on its composition and purity, there are kinds that are not magnetic. For example, Steel is mostly Iron, Carbon, and a few o…ther lesser materials, and can be magnetic. Pure Iron is of course magnetic. The iron in your blood, however, is not the magnetic variety. It all depends on the composition.
Other than iron, steel, nickel and cobalt may be attracted to a magnet
Magnets are used in computer hard drives, recording tapes, cabinet door latches, electric motors, certain types of bearings, MRI machines, and stereo speakers. In addition, th…e operating principle of compasses that guide people in navigation is based on the magnetic field of the earth. Everyday uses for magnets include: to pick up small objects that react to a magnetto post decorations or important mementos on a refrigeratorto keep kitchen drawers and cupboards closedto entertain or teach your childrenfound in certain household devices
