Hello! This is my first post on Physics Forums. Seems like a good community. I will endeavour to contribute.
Over the next few weeks I will have to build a test rig for a fiber-optic sensor I'm developing. The sensor is for high magnetic field strengths, so the test rig must essentially produce a strong (up to 5 Tesla!) uniform static magnetic field.
My plan is to construct the high-current solenoid with suitable core material, then have a small hole bored along the central length of the core, in which the fiber sensor can sit for maximum magnetization.
I don't know a great amount about the commercially-available selection of core materials.
My question is, basically, what is the most suitable core material for my application? Consider that the saturation induction must be very high (5 Tesla), relative permeability should obviously be large, and the material does not have to be suitable for high-frequency applications. Price is not an issue, within reason.
Many thanks for any suggestions/advice.
Philip
