(4) CPU in the module starts to release the connection
(5) Turn the light bulb on
(6) Light bulb heats the SMA
(7) If the force of SMA coil + spring force > magnetic force, then connecting plate moves down.
(8) Magnetic force is small enogh to detach the upper module
(9) SMA coil is cooled down
(10) Detachment complete
