A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field.
Hardware disease in livestock is traumatic puncture of the gastrointestinal tract with resultant spread of infection, caused by ingestion of a sharp, hard object, usually a piece of hardware (hence the name). These pieces of metal settle in the reticulum and can irritate or penetrate the lining. [1] It is most common in dairy cattle, but is ...
A MEMS magnetic field sensor is a small-scale microelectromechanical systems (MEMS) device for detecting and measuring magnetic fields ( magnetometer ). Many of these operate by detecting effects of the Lorentz force: a change in voltage or resonant frequency may be measured electronically, or a mechanical displacement may be measured optically.
Induction loop. An induction or inductive loop is an electromagnetic communication or detection system which uses a moving magnet or an alternating current to induce an electric current in a nearby wire. Induction loops are used for transmission and reception of communication signals, or for detection of metal objects in metal detectors or ...
A magnet induces circular electric currents in a metal sheet moving through its magnetic field. See the diagram at right. It shows a metal sheet (C) moving to the right with velocity v under a stationary magnet. The magnetic field (B, green arrows) of the magnet's north pole N passes down through the sheet.
A metal detector is an instrument that detects the nearby presence of metal. Metal detectors are useful for finding metal objects on the surface, underground, and under water. A metal detector consists of a control box, an adjustable shaft, and a variable-shaped pickup coil. When the coil nears metal, the control box signals its presence with a ...
After years of investing in self-checkouts, Five Below, Dollar General and others are refocusing on human cashiers, citing long-running concerns about lost inventory.
Electromagnetic shielding. Electromagnetic shielding cages inside a disassembled mobile phone. In electrical engineering, electromagnetic shielding is the practice of reducing or redirecting the electromagnetic field (EMF) in a space with barriers made of conductive or magnetic materials. It is typically applied to enclosures, for isolating ...
