摘要：

Experimental evidence of the nonreciprocal Tellegen magnetoelectric effect is presented. The measured particle consists of a small ferrite sphere and a small piece of a thin metal wire glued to the sphere. The whole system is magnetized by a permanent magnet. The Tellegen effect was observed experimentally when this particle was positioned in a rectangular waveguide and excited by a small wire loop. This result experimentally confirms by a direct observation in the microwave range the known theoretical conclusions and experimental evidences at low frequencies regarding mistakes in some theoretical papers that claimed nonexistence of the Tellegen effect.
