Magnetic Switch Protection (MSP) MSP devices made with Metglas 174; cores have dramatically enhanced the reliability and overall lifetime of pulse power systems. By using a saturable reactor in series with either a semiconductor or thyratron switch, the circuit designer can reduce losses in the switch and extend its life.The saturable reactor is designed to hold off current until the switch
This is a DIY kit for building a 32 bit ferrite core memory. Magnetic core memories were the predominant form of computer memory from the mid 50s until the mid 70s. They work by storing information into the magnetic field of a ferrite core. It is non volatile, meaning that it preserves its contents even when power is turned off.
A magnetic core is usually surrounded by carefully arranged windings of wire. The combination of magnetic core and windings results in a measurable property called inductance. There are various types of soft magnetic materials as well as different types and shapes of magnetic cores. Magnetic cores plus their windings can be thought of as
C cores are formed in the process of winding the transformer strip onto a mandrel, followed by hot made and synthetic processes of cutting the resin bond core. The wound core form is best suited to the magnetic induction current operation and the material grain structure is more easily used compared to the sheet stamping core of different shapes.
The values of thermal resistance of main core shapes for ferrite transformers, cooled by natural convection in air (no forced cooling) are given in the tables below. 1) 2) 3) Empirical data given by Epcos (see image) suggest that in the first approximation the thermal resistance is proportional to the reciprocal of square root of the ferrite core volume.

Magnetic core memory was the predominant form of random access computer memory for 20 years between about 1955 and 1975. It was part of a family of related technologies which bridged the gap between vacuum tubes and semiconductors by exploiting the magnetic properties of materials to perform switching and amplification. Such memory is often just called core memory, or, informally, core.
Core memory uses toroids (rings) of a hard magnetic material (usually a semi hard ferrite) as transformerc
magnetic core behavior is essential to (a) optimize the magnetic device design, and (b) properly model its behavior in the circuit application. The Purpose of the Magnetic Core The fundamental purpose of any magnetic core is to provide an easy path for flux in order to facilitate flux linkage, or coupling, between two or more mag
