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.
当金属物体接触到一个交变的电磁场时，涡流会使这个物体加热。
In order to do so, superparamagnetic particles which connect to the alternating magnetic field are added to the resin of the starting material (1).
为此，可接入交变磁场的超顺磁性颗粒被添加到起始原料（1）的树脂中。

On the basis of different generating heat mechanisms and conditions, absorbing microwave and alternating magnetic field are used to generate heat effect.
根据材料的发热机理和生热条件的不同，经常利用的生热条件是吸收微波生热和在交变磁场作用下的磁致生热。
