A magnetic field viewer recording 3 different axes of a specific value of magnetic flux.
Magnetism projects – to do list
This is a wish list of magnetism projects in no particular order. Some small and interesting to me and others to try things I have not seen on the net before.
“Continue reading” to see my eclectic wish list of future projects.
Mapping magnetic fields with a PICAXE based processor and a Hall effect sensor is being developed. Good pictures already but lots more to explore. Need to replace two of the 3 axis sensors.
First Halbach array made and page started. This arrangement of single magnets puts most of the external field on one side. Tricky to keep the magnets there though. Might lift the pyrolytic graphite better.
Pyramidal magnet array to increase field strength. I have achieved a 10% increase with a progression of smaller magnets but fields of up to 5 Tesla have been achieved with this technique. I have ordered some pyramidal magnets of opposing polarity. It should be interesting to see how strong a field they can achieve.
Paramagnetism page started. with a few elements tests with interesting results. Paramagnetism topic. So far have Titanium, magnesium and LOX. Need water demo and other metals.
Diamagnetic Levitation with Pyrolytic Carbon using thicker 3mm from Scitoys. I’ll try the copper first but only one tenth of the diamagnetism of Bismuth so tolerances will be tight. I need to remake my setup using bigger magnets
Earth magnetic field mapping ?Arduino 3 axis sensor. Around car or a large loop conductor.
I need to perfect the normal field meter first.
Now my new Samsung phone has an app to measure Earth’s 3 axis magnetic fields. Must start a new page. Done
Test mag strength in large electromagnet with Tesla meter (above). Steel saturates at about 2 Tesla so I hope my new meter can read this.
Tesla meter to posts. Need a post of it’s own as I already have 47 photos to edit.
Calibrate prev Tesla meter/Gaussmeter – having trouble with this.
Arc in magfield of big electromagnet.
There are a few more superconducting experiments to do but these need to be planned before I get more LN2.
Electromagnets. I want to get a feel for what strengths various electromagnets are.
Helmholtz coils for a homogeneous field.
Get my commercial Levitron going and use that knowledge to get my own running. Currently in Failures.
I would like to measure peak fields in the 10 Tesla range. I had calculated that I would get 7 Tesla in my can crusher at peak. Now if I can get to 12 Tesla continuous then I might start levitating frogs.
I have a few plans for this lodestone. Firstly, to demonstrate it’s use as a compass. Secondly, to map the field with my magnetic field meter. Finally, to demagnetise it and prove that a lightning-like intense current of 100,000 A can re-magnetise it.
I have thought of having a seat with a number of these magnets in a tube supporting each leg. You could put several in each leg to add the 15 kg force. Three magnets in each leg would give 30 kg each or 120 kg total.
I would like to measure the field from our local MRI machine which I think is less than 2 Tesla.
My big electromagnet could be used for interesting projects with plasma in a neon tube or liquid oxygen.
Describe my magnet separator in NIB Magnets section. Done.
Plenty more magnetism projects on my bucket list.
