This study focuses on the dynamical behaviour of magnetic-field-sensitive p
olymer gels. These gels have been prepared by introducing nanosized magneti
c particles into polymer gels homogeneously. We have studied the kinetics o
f the motion of magnetic gels. The highest working frequency of magnetic ge
ls has been established, and a simple, completed Kelvin model was suggested
to describe the dynamical behaviour. (C) 1999 Elsevier Science Ltd. All ri
