Parameters of mechanical model.

Item	Value	Definition
𝑙	0.1 m	Length of the beam element
𝐸	9×10^5 N/m^2	Young’s modulus of beam element
𝐼𝑧	6.36×10^−11 m^4	Moment of inertia in 𝑧 direction of beam element
𝐼𝑦	inf	Moment of inertia in 𝑦 direction of beam element
𝑚	0.002 kg	Tip mass
𝜁	0.865	Damping ratio of model, the otolith and hair cells are surrounded by endolymph, the damping is simplified as a large value viscous damping
𝑧0	0.02 m	The relative coordinate of the two magnets in 𝑧 direction
