They observed that the application of a sufficiently large magnetic field to this material suppressed spin waves associated with the long - range order, and drove it to an unusual excited state. (europeanspallationsource.se)
Also, external electromagnets are capable of generating larger magnetic field strengths than is possible for planar microcoils, but their large size translates into much smaller magnetic field gradients and their larger inductance leads to slower switching times.» (sciencedaily.com)
Specific sources of other cosmic rays can not be determined easily, because large magnetic fields in the galaxy scatter the rays in all directions. (science.howstuffworks.com)
