102 - Magnetic Field Analysis of a Magnetic Sensor	Module:ST	2011-01-17
Magnetic sensors are used as highly durable and reliable open/close switches to meet the current demands for a variety of electrical equipment and home appliances.An open/close switch combines a detection component and magnet to detect a position using the magnetic flux variations when the information is accessed by the detection component.Selecting the appropriate detection component and magnet as well as evaluating the be arrangement is necessary during the design stage to obtain highly sensitive and accurate location detection.This example presents the use of a magnetic field analysis to evaluate the magnetic flux density distribtion in both the horizontal and perpendicular directions of a magnet.

28 - Magnetic Field Analysis of a Speed Sensor	Module:TR	2011-01-17
Magnetic sensors have been used as automotive sensors.It is important that the accuracy, sensitivity and the responsiveness of the sensors must be ensured while the car is operating.The sensor performance improves if magnetic core is placed close to the wheel. However, it is also important to have adequate distance between them to avoid some dirt or foreign objects from being stuck.This note presents the use of magnetic field analysis to evaluate the voltage signal that varies with distance.
