Hall Effect Sensor We could not end this discussion on Magnetism without a mention about magnetic sensors and especially the very commonly used Hall Effect Sensor. The hall effect sensor is a type of magnetic sensor which can be used for detecting the strength and direction of a magnetic field produced from a permanent magnet [...]
Magnetic Reed Switch Construction Magnetic reed switches are electromechanical devices that open and close electrical circuits in response to magnetic fields. Their construction is critical to their functionality and reliability. The following details outline the key components and configurations of magnetic reed switches. 1. Basic Structure A typical magnetic reed switch consists of two or [...]
What is a Magnetic Reed Switch and How does it Work? What is a Magnetic Reed Switch? A magnetic reed switch is an electromechanical device that operates by the presence or absence of a magnetic field. It consists of two ferromagnetic metal contacts, known as reeds, which are hermetically sealed within a glass envelope. The [...]
On and Off, Off and On: Magnetic Switches How are magnets used in switches, and why are magnetic-powered electric switches important? “On-Off” switches are about as ubiquitous as traffic lights, conventional light switches, and stop signs. Around the world, people frequently interact with these everyday and mundane — yet very important — tools. Something as [...]
1. What is a magnetic sensor? A magnetic sensor usually refers to a sensor that converts the magnitude and variations of a magnetic field into electric signals. Magnetic fields, as exemplified by the magnetic field of the earth (earth magnetism) or magnets are familiar yet invisible phenomena. Magnetic sensors that convert invisible magnetic fields into [...]
Magnets in Sensors Demonstrated Value of Magnets in Sensors and Everyday Uses Driving a car, talking into a microphone, inserting coins into a machine — these common, mundane activities may seem completely unrelated, but there’s one shared element at work that may not cross your mind: the presence of magnets. More specifically, magnets are present [...]
Magnets for Sensors The line of magnets for sensors is designed to meet the requirements of non-inductive sensor manufacturers that need position, level, adjustment and distance detection. Magnets for sensors of equal dimensions offer constant switching through time at greater distances from the sensor. Aluminium or non-ferrous metallic walls do not compromise switching. Furthermore, they [...]
Applications for Neodymium Magnets Since their discovery, in the early 1980s, neodymium magnets have become the most widely used of the many varieties of magnets. They can be found in several everyday devices from disk drives to magnetic parts of cars and airplanes. Neodymium magnets can be produced in any size but retain their initial [...]
How Does Temperature Affect Magnetism of Magnets? - Magnets are used in daily life. They’re used in manufacturing, automobiles, security systems and electronics devices. Even the earth itself is a magnet. How does temperature affect the magnetism of magnets? To understand temperature effects, we need to look at the atomic structure of the elements that [...]
Magnets Safety Advice Warning! Magnets should be handled with care and treated with respect. Keep individual magnets well separated from each other and do not place magnets near steel tools, benches or other ferrous objects. There are various ways in which magnets and magnetic equipment can be a dangerous hazard. Larger Magnets: Larger magnets must [...]

Magnet Common Sense As we all know, magnets are very useful in our daily life. To let those who are new to the world of magnets have a better understanding of them, in this article, we’ll introduce some common sense of magnets. A Brief History of Magnets The ancient Greeks and Chinese discovered a naturally [...]
