Imagine a tuned cavity i.e. a bell. When it is struck, it provides a sound wave of fixed frequency. If it is struck several times a second, it provides the same frequency at a much higher volume. The striking of the bell is known as the pulse repetition frequency (PRF) and it is this that dictates the power output of a magnetron. The dimensions of the cavities govern the output frequency. Instead of striking a magnetron, it is pulsed across its anode and cathode by a high DC voltage. This is the energy input that equates to the striking of the bell. The gap between the cathode and anode is a vacuum. Electrons being emitted by the heated cathode each time it is pulsed or 'struck' transfer the energy to the cavities. These electrons bunch in reaction to the tuned frequency of the cavities, forming spokes circulating the cathode. Eventually, the electrons strike the anode and cause the cavities to 'ring' at the tuned frequency. One of the cavities has a loop that extracts the energy into a coax/waveguide.

Why bjt is called current controlled current device?
Because the operation of the transistor is determined by the current at the base. the principle equations of BJT operation are: Ic = h*Ib ,and Ie=Ib+Ic thus device operation is controlled by the input current.

Principle and operation?
principle refers to the basic objective of something. Operation refers to how it operates.
Principle of operation of magnetron?
A magnetron operates by using a magnetic field to control the movement of electrons emitted from a heated cathode. When these electrons are influenced by the magnetic field, they spiral outward and interact with a series of resonant cavities, generating microwave radiation through the oscillation of the electrons. This microwave energy is then extracted and directed for various applications, such as in microwave ovens or radar systems. The design allows for efficient conversion of electrical energy into microwave energy.
How do you replace the magnetron on a GE JVM1870SK microwave?
To replace the magnetron on a GE JVM1870SK microwave, first, ensure the appliance is unplugged to avoid electrical hazards. Remove the outer casing by unscrewing the necessary screws, then disconnect any wiring connected to the magnetron. Carefully unscrew the magnetron from its mounting and replace it with a new one, reattaching the wiring and securing it in place. Finally, reassemble the microwave's outer casing and plug it back in to test the operation.
Should the outside of a microwave ever be hot?
It can be. The magnetron tube inside gives off heat as a result of its operation, so that heat has to go somewhere.

What is a magnetron made out of?
A magnetron is typically made out of a vacuum tube with a cathode, anode, and resonant cavities. It also contains a magnet to generate a magnetic field that helps in the operation of the device. Materials commonly used in its construction include metal, ceramic, and insulating materials to maintain a vacuum.

How do you test a magnetron in microwave oven?
To test a magnetron in a microwave oven, you can use a multimeter set to the resistance or continuity function. Disconnect the magnetron from the oven and touch the multimeter probes to the terminals on the magnetron. If there is no continuity or the resistance reading is significantly different from the specified range, the magnetron may be faulty.
