A reed is a type of switch that uses a magnetic field to activate its contacts. It consists of two metal blades (reeds) that are held together in a sealed glass envelope. When a magnetic field is applied, the reeds come together and form an electrical circuit.
A "magnetron" is a type of vacuum tube used to generate high frequency electromagnetic waves. It consists of a heated cathode and several electrodes arranged in a vacuum chamber. When a high voltage is applied to the electrodes, electrons are emitted from the cathode and accelerated towards the anode. This acceleration causes the electrons to emit electromagnetic radiation.
