The basic principle of implementing inductance resonance test device is to change the parameters of inductance components,so that it can form a resonant circuit together with capacitance components.There are several specific implementation methods:
 

　　Adjust the physical structure of the coil:The tuning coil is an inductive component.By changing factors such as the number of turns,the shape,and the material of the coil,the inductance value of the coil can be changed to achieve the tuning effect.

　　Use variable inductors:Variable inductors are components that can change their inductance value through mechanical or electronic means.By changing the structure of the variable inductor or adjusting the position of its internal inductive element,the inductance value can be changed to achieve the tuning effect.

　　Use adjustable inductors:Adjustable inductors are components with adjustable inductance values.By adjusting the parameters of the adjustable inductor,such as knobs,switches,etc.,the inductance value can be changed to achieve the tuning effect.

　　Use magnetic materials:By introducing magnetic materials into the inductive component,the inductance value can be changed by changing the magnetization degree of the magnetic materials,thereby achieving the tuning effect.

　　Use electronic components:By using electronic components such as controllable inductors,transformers,etc.,the inductance value can be changed by controlling the working state or parameters of the electronic components,thereby achieving the tuning effect.

　　It should be noted that the specific methods of implementing tuning will vary depending on the specific requirements and designs of the experimental setup.The above methods are just some common implementation methods.
