Смысл: The main idea is that by utilizing residual magnetism and the orientation of magnetic domains, it is possible to create locking mechanisms that maintain a strong hold without continuous power, requiring electricity only for the state transitions of locking and unlocking.
The article explains how residual magnetism allows for the creation of electromagnetic locks that stay closed without constant power, requiring electricity only to lock or unlock.
Смысл: The text introduces a novel modular robot design that achieves mobility and self-assembly through internal kinetic energy (flywheels) and magnetic attraction, paving the way for autonomous swarm robotics.
MIT researchers developed M-Blocks, robotic cubes that use internal flywheels and magnets to move and self-assemble into complex structures without external moving parts.
Смысл: The text explains that ferrofluids are superparamagnetic colloidal solutions that react to magnetic fields without retaining magnetization, and describes their use in speakers and smart dampers.
An introduction to ferrofluids, explaining their superparamagnetic nature and their applications in high-end audio equipment and automotive suspension.
