The field will be DC (static) but very strong.
I am not knowledgeable about core materials. I know the standard material is iron ferrite.
What is the most suitable core material for my application (very strong field, very low rate of change)? Expense is not an issue, within reason.
Many thanks.
Philip|||You cannot use any core material (it would just saturate). The strongest magnet in existance is 30 Tesla, and MRI magnets are usually about 2 Tesla. Superconductors tend to be marginal at 5 T field levels (they lose their superconducting properties), so your best bet is just to use copper tubing with coolant circulating through it. You need many, many megawatts of power to do this. The most uniform field you are going to get would be using a Helmholtz coil geometry.|||LOL! Thanks for the comment. A 2T field will already be a major challenge and considerable capital If you really did ALL the calcs, turns, amps, wire gauge power source, you should know that. Keep me posted.

|||It reads like you have no idea what you are after. A 5 T field will saturate any magnetic material on the market by a factor of 10.
If you would have done any calculations,
Field = 1,3 10^-8 x turns x current^2
you would have realized the difficulty of your task. It would require untold amounts of copper, current and power to achieve such field.
You may be able to generate high magnetic fields in short bursts. A magnetic core would be useless.
