    After the reaction, assuming you completely use up the iron, the only magnetic attraction can come from the paramagnetic attraction of the iron(II) as part of the compound. Iron(II) is a d 6 ion, which, depending upon the spin state (high spin or low spin), will have five or one unpaired electrons.

    Apr 01, 2010· I believe iron, cobalt and nickel are the only magnetic metals. Why is this and is a coincidence that they are next to each other on the periodic table?


  • Why Does a Magnet Attract Iron? | Sciencing

    Yet few people can explain exactly why iron has this magical relationship with magnetism. To arrive at the answer, you need to get down to the atomic level and examine the magnetic nature of an atom's electrons.


  • Why is iron magnetic? | Yahoo Answers

    Mar 11, 2010· Iron is ferromagnetic because, while the atoms do not have their electron spins lined up at room temperature, it is easy for an applied external magnetic field to torque the atoms around until they all line up with the field.

  • Why Is Iron Magnetic and Wood Not? | Reference.com

    Each atom of iron has an unpaired electron whose spin can be lined up to that of the unpaired electron from a neighboring iron atom. The spinning of the charged electron creates a magnetic moment, which in turn can align with an external magnet, thus making iron magnetic.


  • Ferromagnetism - HyperPhysics Concepts

    Ferromagnetism Iron, nickel, cobalt and some of the rare earths (gadolinium, dysprosium) exhibit a unique magnetic behavior which is called ferromagnetism because iron (ferrum in Latin) is the most common and most dramatic example.


  • When does an iron rod become magnetic? | Socratic

    Consider a piece of iron as composed of tiny magnets (atoms with dipole moment due to the spin of the electrons) disposed in "domains" which are volumes where the tiny magnets are aligned. The fact is that these domains are a lot and in them the magnets are aligned BUT in total they "neutralize" magnetically the entire piece of iron (to "naturally" reach a "lowest energy state").


  • Why are Iron, Cobalt and Nickel Magnetic? | Physics …

    Apr 18, 2010· liquid oxygen is also magnetic, I would like to know what causes the magnetic field in a neutron. And when iron is heated red hot,a magnet wont stick to it . This is why at the steel mill they have to pick up the slabs with tongs when they are hot, but when they cool you can pick them up with an electromagnet.


  • Why is iron magnetic and wood not? | Yahoo Answers

    Oct 16, 2006· Thus the Iron atoms act like little tiny magnets, and if you put them in a magnetic field (by putting a magnet against them) the atoms will line up so that a big magnetic field is made. This is a basic property of Fero-magnetic materials.


  • Magnetite - Wikipedia

    Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, …


  • Iron - University of Denver

    A property of the iron family for which there is no substitute at an equivalent cost is that they can be induced to provide a strong magnetic field with only small excitation by an electric current. It is a very remarkable property, so an effort will be made to explain how it arises, and how it is used.
