Earth’s Magnetic Field Reversal Earth’s Magnetic Field Reversal Took Three Times Longer Than Thought A new study suggests the last field reversal 773,000 years ago took 22,000 years to occur, which could explain some of the inner workings of our planet’s core。 Earth’s magnetic field is known to flip direction with a somewhat unnerving regularity: [...]
What Is a Magnetic Switch? A magnetic switch is just like a light switch: it turns a circuit on or off depending on what position the arm of the switch is in. The only difference is that a magnetic switch is operated by a magnet, rather than your fingers. Parts A magnetic switch has an [...]
Selective Catalytic Reduction ( SCR ) System AdBlue Resistance Magnet What is Selective Catalytic Reduction? Selective Catalytic Reduction (SCR) is an advanced active emissions control technology system that injects a liquid-reductant agent through a special catalyst into the exhaust stream of a diesel engine. The reductant source is usually automotive-grade urea, otherwise known as Diesel [...]
