  In very intense magnetic fields, $B > 1.5\times 10^{14}$ T, the breaking of
the strong interaction $SU(2)\times SU(2)$ symmetry arranges itself so that
instead of the neutral $\sigma$ field acquiring a vacuum expectation value it
is the charged $\pi$ field that does and the magnetic field is screened.
Details are presented for a magnetic field generated by a current in a wire; we
show that the magnetic field is screened out to a distance $\rho_o\sim I/f_\pi
m_\pi$ from the wire.
