Eddy Currents are little circles of electricity created when metals are moved by magnets or even when magnets are moved by metals. To understand this practically take a regular piece of cardboard and drop it in between a horse shoe magnet. It drops normally with out being effected by the magnet. This is because the cardboard does not conduct electricity. Therefore it does not cause any eddy currents. But instead if you use an aluminum piece in the same way, it falls very slowly, because alumi...

Planning on getting the iPhone 5, but want to keep your SIM card? The new nano-SIMs that manufacturers are adopting will be even smaller than the micro-SIMs that most of us currently use. It's fairly easy to cut a regular SIM down to a micro-SIM, but because the nano-SIM will be thinner as well as smaller than the micro, cutting it down to size will require a little more work.

This tutorial the shows how to find out the measure of an exterior angle of a regular polygon. He shows the formula to find it which is 360/n, where n is the number of sides of the regular polygon. He goes on further to explain the formula by taking an 18-sided regular polygon as example and computes its exterior angle as 360/18, which is 20 degrees. If you are looking to compute the exterior angel of a regular polygon, follow the procedure given in this tutorial.
