A small DC inductor is typically limited more by the cores available window area than its cross-section area. The cores window must be large enough to accommodate the number of turns of wire required to reach the specified inductance. A large DC inductor is often limited by the cores saturation point.

In 1953, MITs Whirlwind becomes the first computer to use magnetic core memory. Core memory is made up of tiny donuts made of magnetic material strung on wires into a grid. Each core stored a bit, magnetized one way for a zero, and the other way for a one. The wires could both detect and change the state of a bit.

2020-1-3The precast concrete industry has been searching for a more economical and efficient formwork method. In the past, some conventional magnets were used to position and fasten the formwork, but considerable mechanical loads with a hammer were required, which was easy to damage the magnets and the surface of the expensive formwork tables as well.
