Abstract: We present measurements of the Faraday and the Cotton-Mouton effects of helium gas at $\ensuremath{\lambda}=1064$ nm. Our apparatus is based on an up-to-date resonant optical cavity coupled to longitudinal and transverse magnetic fields. This cavity increases the signal to be measured by more than a factor of 270 000 compared to the one acquired after a single passage of light in the magnetic field region. We have reached a precision of a few percent for both the Faraday and the Cotton-Mouton effect. Our measurements give the experimental value of the Faraday effect at $\ensuremath{\lambda}=\phantom{\rule{0.16em}{0ex}}1064$ nm. This value is compatible with the theoretical prediction. Concerning the Cotton-Mouton effect, our measurement agrees at better than 1$\ensuremath{\sigma}$ with theoretical predictions.
