Abstract

The forces of interaction between samples of magnetoactive elastomers (MAE) and hard magnetic composite seals based on neodymium–iron–boron (NdFeB) particles are investigated. The force of interaction between an MAE tape and a seal with 90% NdFeB particles is comparable to the one between an MAE tape and a seal based on cooriented permanent magnets. Composite materials based on NdFeB particles allow seals of any shape to be prepared. Composite seals are more convenient for use in surgery as an element of a magnetic retina fixator.
