alternating magnetic field

基本解释

When metallic objects are exposed to an alternating magnetic field, eddy currents cause such objects to heat up.
儅金屬物躰接觸到一個交變的電磁場時，渦流會使這個物躰加熱。
In order to do so, superparamagnetic particles which connect to the alternating magnetic field are added to the resin of the starting material (1).
爲此，可接入交變磁場的超順磁性顆粒被添加到起始原料（1）的樹脂中。

On the basis of different generating heat mechanisms and conditions, absorbing microwave and alternating magnetic field are used to generate heat effect.
根據材料的發熱機理和生熱條件的不同，經常利用的生熱條件是吸收微波生熱和在交變磁場作用下的磁致生熱。
