What is the force that can cause two pieces of iron to attract each other?

Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field. The piece of iron has become a magnet.

What is the difference between and ordinary piece of iron and a piece of iron that is magnetized?

Under normal conditions, a magnetic material like iron doesn’t behave like a magnet because the domains don’t have a preferred direction of alignment. On the other hand, the domains of a magnet (or a magnetized iron) are all aligned in s specific direction.

What material makes the strongest magnet?

neodymium
The strongest permanent magnets in the world are neodymium (Nd) magnets, they are made from magnetic material made from an alloy of neodymium, iron and boron to form the Nd2Fe14B structure.

How will you distinguish two identical bars of iron as a permanent magnet and an ordinary piece of iron?

So when we are given two identical looking magnets and iron rods, one way to distinguish between them is by the magnetism property of a magnet. Both the rods can be placed near a pin or steel rod which will be attracted by the magnet. Iron will not have any response for this.

When the same poles of two magnets whether north or South are placed close to each other they?

In other words, if you hold two magnets together so that like-poles are close together (two norths OR two souths), they repel.

Is iron a ferromagnetic material?

Ferromagnetism is a kind of magnetism that is associated with iron, cobalt, nickel, and some alloys or compounds containing one or more of these elements. It also occurs in gadolinium and a few other rare-earth elements.

Is iron paramagnetic or ferromagnetic?

There are four basic types of magnetism that a material can have: superconducting, diamagnetic, paramagnetic, and lastly ferromagnetic. Superconducting materials are strongly repelled from permanent magnets….Why are all metals magnetic?

Type of Material	Response to Magnets
Ferromagnetic (e.g. iron, cobalt, nickel)	strongly attracted

Is iron the strongest magnet?

But some substances are strongly magnetic, which means most of their electrons spin in the same direction. These substances have high magnetic permeability and make the strongest magnets. Iron, cobalt and nickel are among these substances. Neodymium iron boron (NdFeb) makes the most powerful magnets.

Which is the easiest way of identifying the iron piece at the earliest?

the easiest way of identifying. the iron piece at the earliest? by suspending the magnets one at a. By conducting repulsion test using.
