Abstract

The invention provides a digital lock ( 100, 1001, 1002 ) including at least two magnets. One magnet is a semi hard magnet ( 310 ) and the other magnet is a hard magnet ( 320 ). The hard magnet ( 320 ) is configured to open or close the digital lock ( 100, 1001, 1002 ). The semi hard magnet ( 310 ) and the hard magnet ( 320 ) are placed adjacent to each other. A change in magnetisation polarisation of the semi hard magnet ( 310 ) is configured to push or pull the hard magnet ( 320 ) to open or close the digital lock ( 100, 1001, 1002 ).
