Why are some iron objects magnetic and some others not magnetic?
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.

Iron Magnatized \n. \nThe "magnitized" iron will have domains aligned to Earth's magnetic field. These magnitized iron will have poles and act like magnets. \nSome other ir…on 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.
electromagnets are used in batteries to convert energy into electricity
Because their domains are lined up or not.
the magnet attracts to iron by the magnetic field both the iron and the magnet have
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.
They stick to things because they both are magenet and dont stick because they are not both magenet
Because it may or may not contain they mineral magnetite (Which is magnetic).
Theres a certain mineral inside them(called magnelite) which causes magnetism, this is present in lava. When the magnet comes near a magnetic surface the magnelite in them ali…gns causing them to 'stick'.
It is because some of the metallic objects are more magnetic than each other(more iron than each other).
Objects that are attracted to a magnet are ferrous metals. This means they are composed of elements like iron, nickel, and silver.
No. It only needs to pass through a magnetic field to become magnetized. It does not need to come into physical contact with the magnet producing that field. This is because t…he process of magnetization has to do with electromagnetic induction rather than physical contact. You can perform a simple experiment at home to prove this point. You'll need a bar magnet, a paper clip, and a thin sheet of paper. Place the paper between the magnet and the clip. Rub the clip against the paper on top of the magnet, and observe that the clip will still become magnetized even though it is not in physical contact with the magnet.
Some objects are not attracted by magnets because they are not metalic. If the Magnet just attracts metalic minerals, definitely only metalic are attracted and not non-metalic…..
cause they are broken in half..
Among American pennies (cents, actually) only the famous wartime steel cents made in 1943 are magnetic. All other US cents are made of metals such as bronze or zinc that aren'…t attracted to a magnet. In 200 Canada changed the composition of its cents to copper-plated steel, so those coins are attracted to a magnet but earlier issues aren't British pennies have been issued in both bronze and copper-plated steel so depending on the year of issue they may or may not be attracted. In some years both compositions were used, which makes things a bit more confusing. Euro cents are all made of copper-plated steel so they too are attracted.
The magnet will induce magnetism, at least temporarily, in the iron.
