We report the results of the search for rapid periodic magnetic variations in $\gamma$ Equ. Observations were collected in August 1989 with the 6-m telescope of Special Astrophysical Observatory (Russia). We analysed a 3-hour series of 1720 rapid $B_{\rm e}$ measurements of $\gamma$ Equ obtained with an average time resolution of 6.6 s. A power spectrum analysis shows a period of $P = 3.596\,{\rm min}$. That period differs from the well-known photometric period of rapid variability $P_{\rm phot} = 12.44\,{\rm min}$. We do not confirm variations of the $B_{\rm e}$ field of $\gamma$ Equ with the $P_{\rm phot}$.To search for other articles by the author(s) go to: http://adsabs.harvard.edu/abstract_service.html
