Magnetic Tweezers#

Magnetic tweezers manipulate microscopic particles using magnetic gradients. Their behavior is powerful but extremely substrate‑dependent.

Dimensional Core (SET)#

• Spin: magnetic moment
• Elec: coil control
• Temp: affects viscosity and drift

Why Red‑Zone#

Magnetic tweezers operate in a highly substrate‑sensitive regime.
Biological samples, fluid viscosity, and magnetic heterogeneity create fragile, nonlinear behavior.

Regime Notes#

• pos‑regime: stable samples, controlled fields
• Q‑regime: heterogeneous particles, drift
• neg‑regime: rapid motion, unstable gradients

Containment Notes#

Requires explicit sample‑stability and field‑gradient boundaries.
