Magnetic sensors can be used as triggers to detonate explosive devices.
Explanation: The statement that magnetic sensors can be used as triggers to detonate explosive devices is True. Magnetic sensors can be used to detect changes in magnetic fields, and they are often employed in security systems and bomb-detection devices.
A magnetic sensor is a sensor that detects the magnitude of magnetism and geomagnetism generated by a magnet or current. There are many different types of magnetic sensors. This section explains the typical sensor types and their features.
An object's "composition" affects a magnetic sensor's ability to detect it. We can define composition of any object as the nature of the ingredients that are included in that object.
Magnetic Induction Sensors is composed of an electromagnetic coil. The amount of the temperature drift is operated, canceled in the converter, and Magnetic Induction Sensors can be suppressed to the minimum though the temperature drift originates in the resistance change according to the temperature of the winding.
How inductive sensors work is the sensor creates an electromagnetic field that emits from the sensor's face. Putting a metal target near the sensor's face will disrupt the electromagnetic field, causing the sensor's output and indicator light to turn on.
Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field. Alternating electric current flows through the solenoid on the left, producing a changing magnetic field.
Magnetic effect of electric current is one of the major effects of electric current in use, without the applications of which we cannot have motors in the existing world. A current carrying conductor creates a magnetic field around it, which can be comprehended by using magnetic lines of force or magnetic field lines.
Advantages of magnetic sensors
They have no moving parts, so they function wear-free, contactless and omnipolar (can detect both north and south poles). Magnetic sensors are insensitive to soiling and also work reliably in fast processes with switching frequencies up to 200 kHz.
The magnetic properties of a substance can be determined by examining its electron configuration: If it has unpaired electrons, then the substance is paramagnetic and if all electrons are paired, the substance is then diamagnetic.
A sensor is a device that detects and responds to some type of input from the physical environment. The input can be light, heat, motion, moisture, pressure or any number of other environmental phenomena.
The magnetic detector or Marconi magnetic detector, sometimes called the "Maggie", was an early radio wave detector used in some of the first radio receivers to receive Morse code messages during the wireless telegraphy era around the turn of the 20th century.
Geomagnetic vehicle detection use changes in magnetic fields on traffic light systems to detect cars, radar technique detects moving vehicles (though it is frequently used for pedestrian detection because the radars are rarely immobile), and laser technique measures the distance of the vehicle from the intersection (or ...
A trigger is an event that causes a sensor to start a measurement cycle. Today's all-in-one 3D smart sensors include a selection of trigger sources to simplify system integration for specific applications.
The exploding-bridgewire detonator (EBW, also known as exploding wire detonator) is a type of detonator used to initiate the detonation reaction in explosive materials, similar to a blasting cap because it is fired using an electric current.
Lens-position sensors respond to magnetic fields. If you place a magnet near these sensors, the magnetic field will interfere with or temporarily disable the sensors.
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.
Conductive and non-conductive targets
There are two categories of targets that capacitive sensors can detect the first being conductive and the second is non-conductive. Conductive targets include metal, water, blood, acids, bases, and salt water.
Magnetic fields are produced by moving electric charges. Everything is made up of atoms, and each atom has a nucleus made of neutrons and protons with electrons that orbit around the nucleus. Since the orbiting electrons ≠are tiny moving charges, a small magnetic field is created around each atom.
Examples of magnetic force is a compass, a motor, the magnets that hold stuff on the refrigerator, train tracks, and new roller coasters.
Answer: The magnetic effect ofcurrent is utilised in making electromagnets,electric bells, telephone instruments, electricfans, electric motors, loudspeakers and toys etc. ... It is this magnetic field produced by the current-carrying wire which exerts a force on the compass needle and deflects it (or moves it).
An emf is induced in the coil when a bar magnet is pushed in and out of it. Emfs of opposite signs are produced by motion in opposite directions, and the emfs are also reversed by reversing poles. The same results are produced if the coil is moved rather than the magnet—it is the relative motion that is important.
The magnetic forces between the two poles of a magnet create a magnetic field. This is the area affected by the magnet. A magnetic field surrounds all magnets.
When a conductor is placed in the changing magnetic field, the induced current in the conductor is termed as Eddy current. We can define it as: Eddy currents are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction.
