Abstract

This paper proposes a new induction heating (IH) coil using Halbach-arranged coils for cooktop. In general, a control inverter is placed on the back side of the coil, but by using the Halbach array coils, magnetic flux leakage to the back of the coil can be prevented without using a ferrite cores for magnetic shielding. Further, the magnetic flux can be concentratedly linked to the pot. First, differences and advantages of the magnetic flux distribution between the conventional IH-coil and the proposed IH-coil will be described based on electromagnetic field analysis. Next, the results of verification of the effect of the Halbach array coil via the prototype for principle verification are demonstrated.

Abstract

Here we describe a device for testing possible influences of high magnetic fields on biological processes, by which alternating-current magnetic stimuli as high as 1.7 T can be administered. Experiments with a simple multicellular organism, the nematode Caenorhabditis elegans, revealed that intermittent exposure to the magnetic fields modestly inhibited the animal's reproduction as well as its post-embryonic development, and caused a marked but transient derangement in its locomotory behavior. Available evidence indicates that alternating high magnetic fields can elicit both chronic and acute biological effects, but that the effects may be well tolerated or compensated for by the living organism.
