The magnetron is an efficient self‐oscillation device for transferring the alternating current electrical energy to microwave electromagnetic energy and being used extensively for radar ,navigation ,microwave ovens ,and etc .The construction of magnetron is simple while its working principle is complex ,which is involved with electric engineering ,high frequency electromagnetic field and complex motion of electrons bunches .The content herein sketches briefly the component construction of magnetron ,analysis method of operation mechanism , resonance frequency and the energy conversion during electrons motion .The starting of micro‐wave oscillation controlled by orthogonal static electromagnetic field is discussed and an analo‐gy is made between the resonance excitation of magnetron and a bow drawing across the strings of a violin .
