Magnetic-Field-Based Self-Assembly

Synonyms

Magnetic assembly; Magnetic self-assembly; Magnetic-field-based self-assembly

Definition

Magnetic-field-based self-assembly refers to the autonomous organization of discrete components to form ordered patterns, structures, devices, and systems driven by an external magnetic field or by magnetic fields from permanent dipoles incorporated into parts. The magnetic-field-based self-assembly approach can be applied for the assembly of individual magnetic components such as magnetic nanoparticles and nanowires. It can also be applied for the self-assembly of multiple components, such as components with complementary micromagnet arrays or a mixture of magnetic and nonmagnetic components.

Overview and Concepts

For magnetic self-assembly, a magnetic interaction between magnetic components is required [1]. The strength of the magnetic interaction force is dependent on the distance and orientation between the magnetic components, the magnetization
