Physics help - calculating energy transfer?

It is fairly easy to produce a static magnetic field of 0.050T in the lab. If an EM wave could be produced with a maximum magnetic field, B0 = 0.050T a) what would be the rate of energy transfer (in W/m2)? b) what would the corresponding maximum electric field be? NOTE: air 'breaks down' at E =... show more It is fairly easy to produce a static magnetic field of 0.050T in the lab. If an EM wave could be produced with a maximum magnetic field, B0 = 0.050T
a) what would be the rate of energy transfer (in W/m2)?
b) what would the corresponding maximum electric field be?

NOTE: air 'breaks down' at E = 3x10^6V/m; that is, sparks will jump across such an electric field
