Single-component plasmas are found to exhibit a reversal in the roles of cyclotron and upper hybrid resonances familiar in neutral plasmas. There is a global resonance at the cyclotron frequency $\omega =\Omega \equiv \frac{\mathrm{qB}}{\mathrm{mc}}$ and a local field cancellation at layers where $\omega ={\Omega }_1={({\Omega }^2-{\omega }_p^2)}^{\frac{1}{2}}$, ${\omega }_p$ being the local plasma frequency. Thermal effects limit the amplitude of the global resonance and produce energy absorption at the $\omega ={\Omega }_1$ layers.
