Numerical simulation of lateral interactions between flexible dipole chains in liquids

摘要

The molecular dynamics method is employed to study the effect of the flexibility of chains of particles in a magnetic suspension on their lateral interactions and the formation of columnar structures in a uniform magnetic field. It is shown that the chain flexibility substantially influences the character of the lateral interactions, whereas the critical distance at which the chains coalesce increases with their length according to a power law with an exponent of 0.05 versus 0.002 typical of rigid chains.
