Radio observations of a sample of EA eclipsing binaries, including early-type main-sequence pairs as well as classical Algol-type eclipsing binaries, indicate the presence of a moderately strong coronal magnetic field, B of about 100 G, between the component stars. This translates to a surface magnetic field of about 1000-10,000 G on one or both stars. This is the first compelling evidence for magnetic fields on early-type stars, apart from the Ap and Bp magnetic stars first detected in 1947.
