Here are some more information for Magnetic Spin: For centuries speed sensors have been used to determine the speed of moving objects. In fact, the very first primitive speed sensors were lengths of rope with a knots tied in them that were tossed over the sides of moving ships to determine how many "knots" the ship was traveling at. However; the advent of the motorized wheeled carriage created the need for a more advanced mechanical speed sensor, such as the type that used a gear and a cable to run a speedometer on an automobile. A Technological Need As time and technology progressed however, the need for other types of accurate speed sensors developed. This in turn led to the development of what is often referred to as the magnetic speed sensor. So how do they work? How can a magnet detect and transmit the speed of a moving object? The Hall Effect It is not just the magnet in a magnetic speed sensor that is used to determine speed but an electrical current that surrounds the magnet as well. There is a certain electrical phenomena called the "Hall effect" that is used to determine the speed of an object with a magnet. An Electrical Current In short, when an electrical current is ran near a magnet and the magnet detects ferrous metal such as iron or steel the electrical current is effected. This electrical effect can then be transmitted by wires to a speed gage where it can be displayed. Gear Toothed Magnetic Sensor Often a gear is used in conjunction with a magnetic speed sensor. As the gear spins or turns, each spline or tooth in it will be detected by the magnet as it passes and a corresponding electrical pulse is sent out. The faster the gear spins the faster the electrical pulses the sensor sends and thus a speed reading is made. About the Author Written by Rosa Telipten. Now you can learn all you wanted to know about Magnetic Speed Sensors and you will even find articles on Variable Reluctance Pickup What does a compass do if you stand with it over the North Magnetic Pole? Does it simply spin round ?. Does it try to point down instead?. And how much stronger is the magnetic field there , compared with the rest of the surface of the earth ,since "all" the Earth's magnetic flux tries to enter the Earth there?
the north seeking pole of the needle will attempt to point vertically downward because the pole is underground(a long way down.If you ever get your mits on a 'dip circle'(a compass with a horizontal pivot you should use it and you will see that in the northern temperate zone the needle dips up to 70degrees from the horizontal.You are right,the field is more intense.
