Where p and q are constants. (i,j,k are the vectors, couldn't seem to do ˆ above them)
Show this is a solenoidal field.
(note: E represents power of ten)
What is the force exerted by the coil on the magnet?
2. Can this slab work as a quarter-wave transformer? if so, at which frequency (or frequencies )?
3. Consider a wave perpendicular incident from air, with electric field amplitude of 1 V/m. sketch the envelopes of the electric and magnetic fields at one frequency where there is no reflected wave in air. Mark the values of the envelops at both boundaries of the slab. Write down the value of the selected frequency.
