Building a Magnetic-Driven Lego Submarine Learn how this RC submarine uses magnetic couplings to transmit torque through its walls without drilling holes ensuring no leaks Watch the full process ...

The researchers are using magnets positioned in trench of the track as a kind of magnetic gear to push against. A series of electromagnets on the Lego vehicle ride in that track. The can be ...

The [Brick Experiment Channel]’s latest build, a submersible made almost entirely from Lego, is one such project ... this time around he built clever magnetic couplings. The couplings transmit ...
