Claim 2:
3. The displacement detection circuit according to claim 2, wherein an amplification factor of the first amplifying circuit satisfies the following formula:

a=2μ0N(4A2h1+2A1h2),

wherein a is the amplification factor of the first amplifying circuit, wherein to is a permeability of vacuum, wherein N is a number of turns of one of the coils, and when the rotor in the maglev rotor system is located in a balanced position, a primary air gap has a width of h1 and a surface area of A1, and the auxiliary air gap has a width of h2 and a surface area of A2.
