Low-frequency oscillations ($<1$ MC) in a magnetized carbon arc were observed in order to study the oscillation mechanisms in a fully ionized, high temperature, high density plasma. The pressure range used is from $10^{-3}$ to $10^{-5}$ torr, and the ion and the electron temperature are $2\times 10^{5}$ and $(3\text{--}11)\times 10^{4}$ °K, respectively, and the electron number density is about $1\times 10^{14}$/cc. At least, four types of oscillations have been detected. They are due to acoustic wave, Alfvén wave, drift wave and $I_{r}B_{z}$-plasma rotation. The frequencies of the acoustic waves are 25, 140, 390 420 and 450 KC, and those of the Alfvén wave, the drift wave and the $I_{r}B_{z}$-plasma rotation are 50, 175, and 280 KC, respectively, at the arc current of 100 A and the magnetic field of 2500 gauss.
