A magnetic amplifier is a device which controls the power delivered from an a.c. source by employing a controllable non linear reactive elements or circuit generally interposed in series with the load. The power required to control the reactive element or circuit is made for less than the amount of power controlled; and hence power amplification is achieved. The non-linear reactive element is a saturable reactor. When used in a combination with a set of high-grade rectifiers, it exhibits power amplification properties in the sense that small ch ....etc

INTRODUCTION:
AMPLIFIER:
A circuit that increases the amplitude of a given input signal is called an amplifier. A small a.c. signal fed to the amplifier is obtained as a larger a.c. signal of the same frequency at the output.Amplifiers constitute an essential part of radio, television and other communication circuits. Bipolar junction transistors and Field effect transistors are commonly used as amplifying elements.
Amplifiers can be classified as follows:
1. Based on transistor conf ....etc
