Neodymium wire instead copper wire for coil?
« on: January 28, 2014, 02:53:38 PM »
Hello,
Just wondering while watching this video:
http://www.youtube.com/watch?v=af5kCaDBmA0
If we use neodymium wire instead will the magnetic field be the same and the experiment will go without the need of electricity?
Mayme this is noob question but i just want to know your opinion?
This is a link where neodymium wire is beeing sold so it exists.

what makes you think Neo wire would make any difference? Neodymium is added as an element to make magnets, like Barium, or Strontium, Cobalt  are also used to make magnets.
Maybe you could get some and test out its magnetic properties.

Are we presuming  that  Neodymium wire is the same material as a neodymium magnet but in a long and thin form, and flexible?

Is this so?

Is it magnetic? Is it even magnetisable?

Not sure if it is the same as the magnets, as the magnets are very brittle. 
If it is the same, we could have more impact resistant neo magnets !! 


On the other hand..    You could try it at home !


Smash a few neo magnets in a cloth to powder with a hammer.


Put the stuff in a small flexible tube/hose...   


ét voila:  A neodymium wire




Edit:


This got me thinking...  This way it is also possible to make homemade graphene or should I say graphite wires ...

Yes, but the direction of magnetisation of all the fragments will be up the creek. The wire will have no overall magnetic field.

The idea of a magnetic coil is interesting. not sure where it goes - possibly somewhere. One can buy neo segments which could be pieced together.


(p.s. You cannot be forgiven for not giving your viola its grave accent by giving your et an acute one ! )

Pardon my French, i knew it had to go somewhere..     ;)


OT:


About the magnetics going all over de place...  I guess when filling the tube, the powder  will sort out the poles.. ??  More or less ?


Or, after stuffing it in real hard..  Give it some high current.. to ( i don't know )  melt, or reset .. haha just thinking out loud.

Well almost forgot this topic...
However this also was my idea so i ordered neo magnets from ebay like this:
http://www.ebay.com/itm/2mm-x-5mm-Cylinder-Earth-Neodymium-Super-strong-Magnets-2x5-mm-N35-Craft-Model-/171024972764?pt=LH_DefaultDomain_15&var=&hash=item27d1e1fbdc
200 pcs. However i received them finally but in one day and they were so tiny i lost them in the house somewhere and couldn't find it so cursed my bad luck and didn't order again. Still hope they will show from somewhere.
