(n)certainties – Die Angewandte – Fall 2008


Fara+-Day :

This is the story of a Faraday cage – the outcome of a machine’s electromagnetic environment involved with “liquid metal”. Essentially, this substance consists of a certain magnetorheological fluid. When subject to a magnetic field, this fluid can change its viscosity and even become solid. Interaction between the nozzles may also take place: when equally charged they repel each other or when charged differently they attract each other in snapping. The machines follow the electromagnetic nature of the environment – they decode it through an existing pattern of charges and their forces. Within this infinite space of forces the leading path for the machine is restricted by a certain angular movement through the field lines. This provides different ranges of density for the faradic cage. Finally there is a fragment with the potential to protect against high EM-fields.
