What data do I need to consider when designing a magnetohydrodynamic boat?

[marco12345a]

I am trying to design a boat using magneto hydrodynamic engine MHD what sort of data should i be taking in account? the voltage, current, electric field strength, the velocity of the boat but what else should i look at ?

I suggest you use Google search terms: "how to build a magnetohydrodynamic motor" and then select a project that suits your needs.
