Consider a magnetic core whose volume is 0.0035 m^3. By applying a certain voltage to the coils, the induction field B in the core increased from 0 to 1.6T. Consider that H is a function of B such that H(B)=63.6exp(1.579B). What is the total energy stored in the core? (round to centesimals)

Consider an incompressible, stationary and fully developed flow where an interface between two Newtonian fluids with different dynamic viscosities exists. Taking surface tension into account there is a discontinuity in the pressure field in the interface between the two fluids.

True

False

Not necessarily true

Not necessarily false
