Thanks Dan

Very interesting link.

Hi Sean

I don't know if that link could help

I sourced some cheap bismuth off Ebay today and will be playing with that, but will have a lookout for some pyrolytic graphite and will check your links.

Hi CLaNZeR, any good results in shieldings unsing this bismuth?? I would need also some magnetic shield for my magnetic exps. I have found on ebay an 250gr block of wismuth. It is possible to melt it into appropriate magnetic shield form you think? Or it would be to order pyrolithic graphit better?

Today, I ordered 99.99% of 1kg pure wismuth. I will try to melt it into small magnetic shield. Someone may be has any hints how to do it best?

Hi Jinis

To tell the truth I have not played with it much, I did a few experiments when I received it and not as powerfull as I had hoped regards repulsion.

I will get back to playing with shielding when I get time.
I decided the other week that I am like a kid in a sweet shop, too many ideas to try that I just taste a bit of everything!. So put all the things I wanted to play with on bits of paper in a hat as such and picked one out. Torbay came out and I am going on fate angle at the moment and gonna see the torbay replication project to the end before being distracted again by other ideas!

Apparently Bismuth melts at very low temp and people have simply placed the Bismuth into a container, placed in boiling water and then poored it into moulds to shape.

No idea what temp the pyrolitic graphite melts at, but have got a couple of small bits here to play with oneday when I got more time.
Only home 2 days a week at the moment, so trying to balance the whole Family/work and fun stuff if you get my drift.

Let us know how you get on.

Has anyone played with diamagnetism materials such as bismuth, instead of using another magnet on a wheel for the Repel action, wonder how the sticky point would act against this?

Short Description:
A diamagnetic substance is one whose atoms have no permanent magnetic dipole moment.  When an external magnetic field is applied to a diamagnetic substance such as bismuth or silver a weak magnetic dipole moment is induced in the direction opposite the applied field.

Diamagnetism is interesting. However, the magnetism used to diamagnetize the material is spoiled, so it's not possible to us the magnets fully potential to make a machine work. I have several "post it" drawings and tests that does not work, but I believe it is other and much simpler ways to make a self sustaining device.

It is however possible to use other materials for diamagnetism. Several thin lead, or even carbon, sheets upon each other works well. The secret lays in the structure of the material, as bismuth is crystalized mostly in one directions you'll get the same effect as many thin sheets of lead.

The diamagnetism is however so weak that the possible power to maintain constant RPM in a motor would be consumed by friction and more - the motor stops.
