Directions: 1. Wrap the wire in a tight, even coil around the bolt. Leave 3 or 4 inches of wire loose at each end. Keep wrapping the wire until you get to the end of the bolt. There may be as many as 3 or 4 layers of wire all the way up and down the bolt. Your electromagnet should look something like this: 2.

Building an Electromagnet

Building an electromagnet is easy: Wrap a wire around an iron core (a nail or a bolt works great) Make sure your wraps are all going in the same direction. The tighter the wraps, the closer they are together, and the more you have, the stronger your electromagnet will be. Have a 3 volt power supply or 6 volt lantern battery handy to connect ...

Back to Basics Hammer Milling and Jet Milling Fundamentals

ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding action is caused mainly by particle-particle collisions, so wear to the mill's internals is less of an issue.

Harvesting Energy from Soccer Balls

According to official soccer rules, soccer balls must have a mass between .41 and .45 g - we will use 0.43 kg as an approximate average. A soccer ball is kicked about once every 12 seconds at a speed of about 25 m/s. The power, in watts, generated by the ball is given by. P = 1/2 × 0.43 kg × (25 m/s) 2 × 1/12 sec = 11.2 W
