MAGNETIC QUICK CHANGE SYSTEM FOR MOULDS, magnetic clamping systems for mould change Electro permanent magnetic quick-change systems are used for fast and safe clamping of moulds in injection molding machines from 50 – 4000 TON, resulting in less machine downtime. All molds, regardless of their shape or weight, can be clamped without any mould modifications. [...]
Magnetic Reversals - Scientists tell us that our magnetic poles have reversed in the past, and that they will again. The last one occurred 780,000 years ago. The average time period between reversals is 450,000 years, but there isn’t really any pattern, it is random. We are overdue by average only. Scientists don’t really know [...]
Magnetic North Pole Basically, the Magnetic North Pole is where a compass points. This is not the northernmost point on the globe. It is a point in the Arctic that is always on the move, reacting to magnetic changes in the Earth’s core. Every few years scientists venture into inhospitable territories to locate the pole. [...]
