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.

What are some magnetic objects?

iron


Why are some pieces of iron more magnetic than others?

It is because some of the metallic objects are more magnetic than each other(more iron than each other).


Why are some iron objects magnetic and others not magnetic?

If the iron atoms are aligned then the object is magnetic, if they are randomly oriented then it is not. How the object was manufactured may be the cause of the difference, but it always possible to intentionally either magnetize OR demagnetize an object.


Why are some objects magnetic and others are not?

cause they are broken in half..

Why do some pieces of iron behave as magnets while others do not?

The "magnitized" iron will have domains aligned to Earth's magnetic field. These magnitized iron will have poles and act like magnets. Some other iron do not behave as magnets because their domains are randomly oriented. This means that the domains do not align and will not act like magnets. This is also the same for other objects that don't behave like magnets.


Why are some objects attracted to a magnet while others are not?

Objects that are attracted to a magnet are ferrous metals. This means they are composed of elements like iron, nickel, and silver.


What are some examples of magnetic substances?

Iron, Cobalt, Nickel First of all, iron (Fe) is a magnetic substance. And so is nickel (Ni), cobalt (Co), dysprosium (Dy), gadolinium (Gd), ceramics as ferrites and others, alloys, some organic compounds, etc.


Witch metals are magnetic?

Some metals that are magnetic are iron, nickel, cobalt, and gadolinium. Some steel may be magnetic if it contains enough magnetic metals.


Why are some planets magnetic while others are not?

Planets that have a magnetic field have: 1) Contains magnetic material like iron, ionized gases, hematite, or magnetite. 2) Has a magnetic current going thru the material. If the planet does not contain enough magnetic material or the material does not have enough magnetic current, there is no magnetic field.


Is a soil magnetic material or a non magnetic material?

it generally depends on the soil content~if it is rich in iron or some other magnetic metals it will magnetize but if it don't it won't..soil is non-magnetic but iron filings in it are magnetic

What is the difference between the magnetic properties of iron and steel?

Iron is ferromagnetic. Perhaps the main thing that can be said of steel is that some stainless steels are magnetic, and some are not. Please see the links.
