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.

Thanks for the feedback!
Iron Magnatized 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.
Yes, because it is magnetic.
Yes, iron is magnetic.
the magnet attracts to iron by the magnetic field both the iron and the magnet have
Refrigerator doors, some cabinet doors (like on an entertainment center), door and window alarms sometimes use magnets.
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 th…em aligns causing them to 'stick'.

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.
Objects that are attracted to a magnet are ferrous metals. This means they are composed of elements like iron, nickel, and silver.
1.Stroking it with a magnet 2. Applying a current to a coil of wire wrapped around the iron
The magnetism of iron is the only the North magnetic pole of the magnet and carbon including little pieces of metal in 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
