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.

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


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.




Because it may or may not contain they mineral magnetite (Which is magnetic).


Magnetite is naturally magnetic. Some call it lodestone.


Magnets can attract some objects made of metal such as iron but not copperand others. Wikipedia has a lot on it.


some objects that are non magnetic are wood, plastic, glass,paper,fabric


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.


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


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.


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.


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


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


aluminum Ans 2 - Aluminium is NOT magnetic. The primary magnetic materials are iron and some steel.


Itwhat object. Some planets do have an inner core that has iron and there is also many other objects that we have not discovered that do contain iron.



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.


Some low grade nephrite jade is magnetic due to iron or mica inclusions.


Those that are attracted to magnets have MAGNETIC DOMAINS - groups of atoms where the magnetic field of individual atoms are all aligned.


No, but some types of iron-ore have a permanent magnetic field.


Iron, nickel, chromium, manganese and cobalt.


All of them except for iron nickel and cobalt.


Because some objects are heaver than others.
