Holmium - Periodic Table of Videos

It was named after Stockholm right?

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.

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

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.

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.

Whos this dude??
