Solenoidal

It is commonly believed that extreme solar activity is provided by the magnetic energy of active regions (Forbes, 2000).According to Thomson’s (or Dirichlet’s) theorem, e.g., Lawrence (), any solenoidal field can be decomposed into current and potential parts.The energy of the latter corresponds to the minimum possible under given …

1. Multi-turn helical coil. The helical (solenoid) is the most common and by far the most efficient coil. The design is relatively simple, since the number of turns defines the length of the heating pattern. The workpiece can be stationary in this type of coil to provide a defined heating band in "single shot heating.".[13] M.
