Yes. In fact, is dangerous. Special tools may be prepared in order to mount a PM system without doing mesh. But with extreme care I hope it can be handled. I should say that each approach has an intrinsic point. In order to answer to skogsgurra, the DC power supply adds cost to the system while...
Thank you sreid!. I will check ....I need to learn and convince myself before starting doing. But this forum was of an extremely valuable help. Thanks again!.
In fact the original idea was to deal with low weight, no power supply (or a small one) and a resonable gap/field uniformity for the applications in mind. Nice problem!.
Hi Guys,
would you please tell me at least very approximately the preis per lb of at least one of the materials mentioned in the list of Jick??. Thank you very much in advance.
Well, at first I would like to thank you all for your valuable comments. It is clear now to me that:
1-An electromagnet should be easier to handle. Since duty cycle is high, coils disipation will have to be considered in detail. However, the counterpart is the the need of a high stable power...
Thank you Guys!. The discussion is very helpful (specialy due to my inexperience in the field). I still wonder about the weight. We will need to move the magnet from one application to other over several meters. This is also a reason to look for a permanent-magnet-based solution and not going...
Hello MagMike and MJR2:
many thanks for your answer!. The diameter of polar faces should be at least 5" in order to reach a reasonable uniformity within a volume space of about 3ml. There is no need to reverse the field. Open access is not critical since a 7" lenght and...
Hello:
I am considering to build a 1.5T magnet for my lab but, I would like to avoid dealing with a power supply & wiring considerations. I found very interesting the discussions posted on threads 340-132216 and 133735. However, I wonder which are the reasons for not using magnetic...
