In a high-resolution electron scattering experiment ten 3+ states in 26Mg have been identified, increasing the world data on M3 transitions severalfold. Differential cross sections have been measured and magnetization current densities and form factors have been deduced. It is found that while the level of agreement of the B(M3) values with shell-model predictions varies from state to state, the summed B(M3) strengths are in good agreement. No overall quenching of the M3 strength is found, and it is concluded that no renormalization of the free nucleon g factors is needed.
