. In paramagnetic substances, with positive susceptibilities, just the opposite
happens. The induced magnetization actually enhances the external eld, i.e B > B

.
For ferromagnetic substances, these considerations are not really applicable because
of the so called spontaneous magnetization because of which the magnetic system
may possess magnetization even in the absence of any external elds.
