Using diamagnetism materials

[CLaNZeR]

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.

Hi Sean,

See this thread here and my answer #5 and study the links there, especially the last one there:

I do not think bismuth would have enough useful effect for you but pyrolitic graphite may be. Both can be ordered, see the bottom of this link: https://www.scitoyscatalog.com/

I have not had hands-on experiments with such graphites yet.

Hi Gyula

Excellent links, many thanks.
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 Sean

I don't know if that link could help

Thanks DanC!

The Wadle and May shield looks like a promising material to have on hand for magnetic experimenting!

I'm not a patent expert, but are the details provided enough for one to replicate the experiment, or is there usually a 'held back' secret?

Is sourcing ingredients like coal slag and silver powder going to be hard?

Anyways,  Here's a clip of the first example experiment from the patent:

Step 1. 35 grams of 30/60 coal slag containing 25% Aluminum Oxide, 25% Iron Oxide, and 50% Mineralized Glass.

Step 2. The coal slag was coated with 15 grams of a six micron (6.mu.) silver powder.

Step 3. Then, 25 grams of white silica powder--250 sieve screen was added to the top of the silver powder

Step 4. Finally, 25 grams of a mixture of pharmacy grade calcium, magnesium, and zinc powder. The 25% of the mixture contains 60% weight of calcium, 28% weight of magnesium, and 12% weight of zinc.

The three elements of step 4 are pharmacy grade and were purchased over the counter at a local drug store in tablet form and then finely ground.

Results of the test:

A test was done using a 21/2 ounce round spherical container 3/4'' diameter.times.11/2'' long of iron filings, a 28 lb pull 3/4'' diameter.times.1/2'' long rare earth magnet, and one 3/8'' thick 4''.times.4'' square sheet of each of the following materials: A. Plastic B. Lead C. Stainless Steel D. Copper E. the sheet covered with the shielding material

The test went as follows:

Each individual sheet of shielding material was set upright. The 28 lb rare earth magnet was held against one side of the shielding material and the iron fillings against the other side. The magnet and the iron fillings were held against each side of the shielding material listed above A-E in the same manner.

The magnet attraction from the 28 lb magnet to the iron fillings on shielding sheets A-D was strong enough to hold the iron fillings and the magnet in place.

The shield element E deflected the magnetic pull of the 28 lb rare earth magnet preventing the attraction to the iron fillings, thus the magnet and the iron filing fall down due the earth gravitation pull.
