I need these articles to do some research.Who could help me? Author:Milan Wayne Garrett 1.Thick Cylindrical Coil Systems for Strong Magnetic Fields with Field or Gradient Homogeneities of the 6th to 20th Order J. Appl. Phys. 38 2563 (1967) 2.Calculation of Fields...

my question is :there is a small and thin ferromagnet. how to calculate the magnet field surround it.

please,nobody would help me?

1. There is a small ferromagnet,so it could product the magnet field. parameter:lenth 3mm; width 2mm ;thick 1mm magnetic susceptibility:2. 2.question If there is a position in three-dimensional space(x,y,z) . This position's magnetic induction is ?How to get it? I need...

who could tell me quench programm(fortran or C++ or matlab)?

the circuit of quench protection is simple.(you could find it in the attachment) MRI: 1.5T ,liquid helium 4.2K, NbTi/Cu . the heating at any point in the cable is integral[(I^2 R) dt] ,I konw how calculate the propagation velocity (longitude,transverse),but how I could get I(CURRENT)...

thank you,I design the quench heater which prevent the superconduct coil from exceeding temperature and high voltage. I don't know how design it.Could you introduce something to me?

Hi,I study protection of superconducting coils.I adopt heaters to protect coils.The circuit is in attachment. There are 6 coils,so I use 6 quench heaters.I want to know how I choose the heaters? It must do the Quench Heater Simulation for protection of superconducting coils before...
