  We study the dynamical Myers effect by allowing the fuzzy (or the dynamical
dielectric brane) coordinates to be time dependent. We find three novel kinds
of the dynamical spherical dielectric branes depending on their respective
excess energies. The first represents a dynamical spherical brane carrying a
negative excess energy (having a lower bound) with its radius oscillating
periodically between two given non-zero values. The second is the one with zero
excess energy and whose time dependence can be expressed in terms of a simple
function. This particular dynamical spherical configuration represents the
dielectric brane creation and/or annihilation like a photon in the presence of
a background creating an electron-position pair and then annihilating back to a
photon. The third is the one carrying positive excess energy and the radius can
also oscillate periodically between two non-zero values but, unlike the first
kind, it passes zero twice for each cycle. Each of the above can also be
interpreted as the time evolution of a semi-spherical D-brane--anti
semi-spherical D-brane system.
