Can an Electromagnet Produce 25T with 500 cm3 and How Much Current is Needed?

AI Thread Summary
Designing a Bitter electromagnet to produce 25T within a 500 cm3 volume is theoretically possible, but it would require significant current, with some labs reporting up to 17MW for their weakest DC field magnets. The feasibility of such a magnet is more about cost than size, as increasing or decreasing dimensions can still yield the same induction with the same electric power. Additionally, larger magnets have the advantage of being easier to cool compared to smaller ones. Overall, achieving a 25T field in a compact design presents substantial engineering challenges. The discussion emphasizes the complexity and resource requirements involved in high-field magnet design.

Hey guys, is it possible to design a Bitter eletromagnet that produces 25T and is approximately 500 cm3 in size? If so, how much current would it require? Thanks in advance for your responses guys..

I am not going to do the math but I will forward you to this article.

This lab builds 20T to 45T magnets and they claim their weakest DC field magnet takes 17MW. 25T is a very serious magnet.
 
Size doesn't determine the magnet's feasibility - "only" its cost...

You can increase or reduce all dimensions, including the experiment volume and the coil volume, and get the same induction from the same electric power.

Well, yes, a big magnet is easier to cool than a small one.
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
