This video tutorial is in the Disaster Preparation category which will show you how to use a map style compass. The first thing is to get your bearings by sight without a map. The arrow on the compass represents the direction of travel, the N on the compass dial is the compass North and the red needle points to the magnetic North. First align the compass N with the magnetic North. Now say you want to go 90 degrees East. Next you align 90 degrees with your direction of travel arrow. Rotate the...
Without good navigational skills, your expedition could lead to failure or result in a dangerous situation. Try to use a laminated map which is better in wet conditions. 1:25,000 scale maps provide the greatest detail. One grid square equals 1 kilometer. Use map keys for reference. Don't mistake boundary walls for footpaths. A compass points to magnetic north and the top of the planet is called true north. Magnetic north is constantly moving and its position relative to true north is differen...

The parts of the compass are a base plate with different measurements for calculating mileage and distance. The magnifying glass is used to magnify things on your map. The arrow at the top of the compass is called the direction of travel arrow. To find the degrees on your compass, use the rotating bezel ring, with North being "0", East being "90", South being "180", and west being "270". The magnetic needle inside has a red magnetic north end, which is used to locate "North", and the black en...
David Wilcox and Caitlyn Szyska demonstrate how to use a compass without a problem. Parts of a compass include the ring, the orienteering arrow, magnetic needle, direction of travel arrow and declination scale. First, hold the compass out in front of you, making sure you hold it level. Move your whole body and point the direction of travel arrow to the object that you want to reach.

How to find your direction without a compass if you are in the Northern Hemisphere. Find cardinal points with an analog watch. It's more effective than a compass, because it's not affected by the earth's magnetic fields.
The trick in the video is that the magnets are made of a conducting material and they connect the battery terminals to the copper wire, so the battery, magnets and copper wire make a circuit that generates a magnet field just in the vicinity of the battery. The geometry means the two magnets are automatically at the ends of the generated magnetic field, where the field is divergent, so a force is exerted on the magnets.
Gravity can be a real pain when you are trying to finish a project and your supplies wind up on the ground.

Build a faraday motor with tips from this how-to video. In the early 1800s, physicist Michael Faraday invented the first device to convert electrical energy into mechanical motion. This is an easily built version of his motor. The magnet sets up a magnetic field, and the electrical current through the screw sets up a separate electromagnetic field around the screw. The two fields react and the result is rotation.
