    Probe
In summary, this person is looking for a hall probe to measure magnetic field. They have tried various suggestions from DT, but are having difficulty finding a good price or a school lab-type supplies website. They are also frustrated because they cannot find a ready-made hall probe that is not too expensive.

Hey,
Sorry this is probably in the wrong section but I couldn't think of a more appropriate one. Anyway, I've spent ages on the net looking for a really simple hall probe - like one which I used back in school measuring a max of upto 1.5 - 2 tesla, and I just cannot seem to find any school lab type supplies websites! Really frustrating! Any ideas? I'm in the UK. Any help much appreciated!

Has one tried searching for magnetometer, gaussmeter, teslameter?

I presume one wishes to measure magnetic field as opposed to current?

Yes, that is correct. I may be addressed outisde the third person too. :)

I've tried your suggestions and they brought some up, but they all seems really expensive (>$100) ! Back in school I had a really simple hall probe which you could hook up to USB and mess around with. Good times. Sigh.

Why not call someone at the school and obtain the model or manufacturer or perhaps even the purchase order?

This might be useful - http://www.gaussmeter.co.uk/hall-probes.html [Broken]

If one wants just a probe.

I think the full system with probe and electronics/processor will be pricey.

Or make a Hall probe and meter :biggrin:

Great resource, DT!

For $25, you can buy a calibrated, linear hall sensor from Allegro Microsystems. These are the cheapest sensors I've come across. They are basically a single chip package that you can easily mount on a board. You with need a 5V power supply (or a DC voltage source) and a meter/display to read the output.

Example: http://www.allegromicro.com/en/Products/Part_Numbers/1321/
Price: http://www21.serrahost.com/AllegroMicroSystems/Detail.bok?no=248

Scroll down to near the bottom of this pricing list: http://www21.serrahost.com/AllegroMicroSystems/StoreFront.bok#distributor

Thanks, all very helpful. I think I'll just postpone my plans for a few months and go back into use the school one for abit when I can. All of the ready made ones seem over $150, apart from the chipset. Might resort to the chipset and just hook it up to my multimeter.

Btw I got a quotation from gaussmeters.co.uk and it was well over £100.

Pricey, but the owner was my experimental physics profeesor way back when before all of these new fangled computer driven labs. You know, when you set the temperature on the blackbody for your infrared spectroscopy lab and come back 2 days later when it has stabilized, then you take data all night until the system craps out.

By the way, he is working an initiative for advanced labs, I plan on donating, anyone else?

You've given me an anxiety attack reminding me of that freakin' thermopile!

(Thermo-pile-of-$#*%! On my deathbed, I'm going to demand that month BACK!)

Me too, the best thing about my lab time was that I had a girl-friend who would come over to the lab, do her homework and genrally keep me company all night while I was taking data and pouring over it to analyze it.

Oh that makes me feel so much better! :ironic smiley:

Not only did you have a girlfriend, you had DATA! A month of lugging liquid N2 up to the observatory--no TA's to be found anywhere--lousy instruction manual--plus nobody else in the class had the same project since we all picked one out of a basket and the better ones had been pilfered by the front rows. Five attempts later, all I had was a completely flat field.

20 years later, I'm still mad!

I didn't say the data was worth anything...almost flunked lab because I couldn't get some of the experiments to work at all.
 

1. Where can I purchase a hall probe?

The most common place to purchase a hall probe is from a scientific equipment supplier or manufacturer. Online retailers such as Amazon or eBay may also offer hall probes.

2. What factors should I consider when buying a hall probe?

When buying a hall probe, you should consider the sensitivity, accuracy, and range of the probe. The type of material and magnet strength may also affect your choice.

3. How much does a hall probe typically cost?

The cost of a hall probe can vary depending on the brand, sensitivity, and features. On average, a hall probe can range from $50 to $200.

4. Can I make my own hall probe?

Yes, it is possible to make your own hall probe using simple materials and tools. However, the accuracy and reliability of a homemade probe may not be as high as a commercially available one.

5. What are some applications of a hall probe?

Hall probes are commonly used in scientific research and industrial settings for measuring magnetic fields, monitoring magnetic material properties, and calibrating other instruments. They can also be used in educational settings for experiments and demonstrations.
