  • Really useful, thanks:)

  • For not so smart people like me, would you please explain what unpaired e- are?

  • @dwip57

    Normally in compounds, atoms join together by sharing / giving / taking e- to form a whole outer shell (e- live in shells around the nucleus.) Normally they hang out in pairs.

    When you have some e- in an atom in a compound which are not involved in bonding, just floating around, they are called unpaired electrons. They cause a small charge on the atom which builds up when you have trillions of them to form a noticeable magnetic field.

  • @fightthepurple Thanks! Got it! and now it makes sense!

  • It was named after Stockholm right?

  • @Drag0nfoxx

    Yes, after the Latin word "holmia"

  • @douro20 - Thanks.

  • I once thought iron, nickel and cobalt were the only elements which were magnetic at room temperature.

  • oxygen is magnetic:)

  • no it isnt, its para magnetic.

    it will be affected by a very strong magnetic force but will not retain any magnetism itself.

    lots of substances demonstrate para magnetism. water is one of them.

    MRI scanners work because of paramagnetism.

  • @gordongate i thought water was diamagnetic

  • @enzyme20056 a diamagnetic substance generates a magnetic field in the presence of an external magnetic field that causes repulsion of the substance, paramagnetism is an attractant response. both para and diamagnetic substances will not retain an intrinsic magnetic field when the external field is removed.

    Water in the presence of extremely powerful magnetic fields will be attracted to the source of the field,

    google magnatars and the lethality of close proximity to a strong magnetic field.

  • If I build a house out of Holmium will it be magnetic?

  • 11bingo11 i agree with you i like your experiments but like blow somthing up its makes the show a bit more interesting

  • Whos this dude??

  • So if iron becomes a magnet when it has unpaired electrons, does this mean any metal can become one?

  • Unfortunately not. If the amount of energy required to pair the electrons (ie overcoming the repulsions between two -ve charges) is less than that the energy gained by pairing them (due to the -ve electons being nearer the +ve nucleus), then they will pair and won't have magnetic properties.

    Any conductive material (including all metals) can be made into electromagnets however, but these need a constant electricity supply.

  • I think iron is the only metal that can be magnetised without electricity. I could be wrong. this is only what i remember from school heheh.

  • There are few other magnetic materials beside iron. nicle is one of them as far as i know. Im not sure if its feromagnetic or just paramagnetic though.

  • I concur - let's see some super-magnetism!

  • should've shown a bit of holminium and just how magnetic it was. Also knowing all the possible uses of super-strong magnets, what is the origin of holmnium and how much supply is there?

  • BLOW SOMETHING UP PLEASEEEE
