12-16 Prove that $\frac{1}{2}\int_V \mathbf{H} \cdot \mathbf{B} \, \mathrm{d}v = 0$, where $V$ is all space, if the fields are produced solely by magnets (i.e., no transport currents). Is the magnetic energy zero?

Starting with Eq. (3.32) , prove that the energy densities of the electric and magnet fields are equal $\left(u_{E}=u_{B}\right)$ for an electromagnetic wave
In a region of space where there are no conduction or displacement currents, it is impossible to have a uniform magnetic field that abruptly drops to zero. To prove this statement, use the method of contradiction: Assume that such a case is possible, and then show that your assumption contradicts a law of nature. (a) In the bottom half of a piece of paper, draw evenly spaced horizontal lines representing a uniform magnetic field to your right. Use dashed lines to draw a rectangle abcda with horizontal side $a b$ in the magnetic-leld region and horizontal side $c d$ in the top half of your paper where $B=0 .$ (b) Show that integration around your rectangle contradicts Ampere's law, Eq. $(29.15) .$
