magnetic amplifier

By the early 1960s most magnetic amplifier efforts were abandoned.

They were not magnetic amplifiers as defined in this article.

Interest in magnetic amplifiers lasted only a short time through the 1950s.

The machine was an experiment in using magnetic amplifiers for computer use.

The magnetic amplifier is a static device with no moving parts.

Magnetic amplifiers are also still used in instrumentation for measuring current.

At the beginning it produced different electrical products, control panels, magnetic amplifiers.

Through this period there were widespread efforts to use magnetic amplifiers as an alternative solid state device.

During the 1950s there was widespread interest in the use of magnetic amplifiers as a solid state switching device.

One advantage to magnetic amplifiers is that they are open in the center and several input lines can be threaded through them.

Magnetic amplifiers were extensively used in electricity power generation from the early 1960s onwards.

However, much of the computer's logic was made out of magnetic amplifiers, not transistors.

Magnetic amplifiers are still used in some arc welders.

Like the magnetic amplifiers, Johnson's "Neuron" design could be used to control several different inputs.

Magnetic amplifiers were widely studied during the 1950s as a potential switching element for mainframe computers.

The magnetic amplifiers were based on tiny magnetic cores with two wire windings.

Solid-state amplifiers can be more compact and efficient than magnetic amplifiers.

Magnetic amplifiers were important as modulation and control amplifiers in the early development of voice transmission by radio.

Magnetic amplifiers were used in aircraft systems (avionics) before the advent of high reliability semiconductors.

The magnetic amplifiers required clock pulses of heavy current that could not be produced by the transistors of the day.

There were cables to be wound from one part of the examination room to another, rheostats and magnetic amplifiers to be adjusted.

The magnetic amplifier was most prominent in power control and low-frequency signal applications from 1947 to about 1957, when the transistor began to supplant it.

The magnetic amplifier is also used as a transducer in applications such as current measurement and the flux gate compass.

The decision to use magnetic amplifiers was made because the point-contact germanium transistors then available had highly variable characteristics and were not sufficiently reliable.
