What is a magnetic amplifier?

Magnetic amplifier or Mag AMP is a type of electronic converter. AMP MAG uses the interaction of electrical currents called electromagnetism, to increase electrical signals without required any movable parts. This variety of power amplifier has been a popular substitute for the vacuum tube and is known for its high reliability in harsh conditions. Basic magnetic amplifiers were built in the 18th century, but until the 20th century these devices saw extended use.

Both United States and Germany have developed reliable Mag AMPS for military purposes during World War II. Over the 1940s and 1950s, magnetic amplifiers replaced many vacuum tubular amplifiers that performed the same general function but were more fragile. While modern transistors are now a primary method of power amplification, magnetic amplifiers are still used in devices that must be resistant to serious conditions.

Magnetic amplifier creates meaningradio frequency signal (RF) when IT is activated. This feature can be used to send basic radio messages. By switching the amplifier and off, the RF signal can be manipulated and received from a distance. For this reason, early radio pioneers experimented using large magnetic amplifiers to transfer Morse code messages across oceans.

Magnetic amplifiers use two duplicate wire spools, each of which is wrapped around the magnetic core. To control the amplifier, one of the coils is under the voltage of alternating current (AC). The circuit that receives amplification, called the "load", is connected to the second coil. When the first coil is powered, which also induces the load in the load, an electromagnetic field is generated.

This setting allows you to control the electrical load without the need for a real physical connection or a mechanical switch. Magnetic amplifiers usually have a doubleSince then, there have been no moving parts that could wear out. For the same reason, AMP MAG is relatively immune to vibrations or shocks and can be used in a harsh environment. Equipment such as ARC welders and industrial power supply sometimes use a magnetic amplifier because of these benefits.

However, the magnetic amplifier has some disadvantages. Size is one problem. Modern transistors can perform the same function as AMP MAG while they occupy significantly less rooms. Also, magnetic amplifiers are not as effective as modern transistors in a solid state that are able to control circuits with very low energy loss. The amplification ability or profit AMP MAG is relatively low compared to newer firm amplifiers.
