The results of a variational renormalisation-group calculation for the magnetic exponent y<sub>H</sub> of the two-dimensional q-state Potts model suggest a simple relationship between y<sub>H</sub> and the exactly known critical exponent y<sub>T</sub><sup>8v</sup> of the eight-vertex model. The relation allows one to predict the critical and tricritical magnetic exponent delta of the q-state Potts model as a function of q.
