The G5 geomagnetic storm of May 2024 provided a significant opportunity to investigate global ionospheric disturbances using vertical total electron content (VTEC) data derived from 422 GNSS-IGS stations and GIM. This study presents comprehensive spatio-temporal analysis VTEC modulation before, during, after the storm, focusing on hemispheric asymmetries longitudinal variations. primary objective this is analyze spatial temporal under extreme conditions, assess asymmetry disruptions,...
A novel use of the LiDAR sensor a smartphone spring in introductory physics experiments is discussed this paper. We have determined constant for various combinations springs using through phyphox application. An electrical heater coil used as spring, and period oscillation vertical spring–mass system measured sensor. The experimental values constants agree with theoretical values. high school student can perform simple experiment smart way at home.
Abstract A smartphone can be used for many physics experiments by using the sensors built into phone. The complementary metal oxide semiconductor (CMOS) (charge-coupled device, CCD) sensor of camera records images objects photographed in pixels. width image read off with micron level accuracy help software available freely from internet. If dimensions object direction transverse to viewing are known, magnification determined accurately. is a compound lens comprising number very thin lenses....
Abstract A novel method is proposed to determine the magnetic moment of a magnet by studying its free-falling motion inside non-ferromagnetic and conducting pipe. The dynamics neodymium falling pipe tracked using sound waves fixed frequency generated one smartphone detecting acoustic resonance in simultaneously other. This tracking technique leads measurement terminal velocity magnet, as interaction between produces force, similar viscous drag, on magnet. result obtained verified torsional...
A smartphone is a powerful learning aid in the hands of large section students around world. The camera phone can be used for several purposes apart from its obvious purpose photographing. If focal length lens determined, experiments optics performed with it. In some recent works, method determination has been discussed. When real image an object formed by known length, one determine either distance or transverse magnification if other known. this work we have shown that both size and...
Abstract We have designed an experiment that involves studying the effects of a conducting plate on motion oscillating disc magnet. employed video analysis method by ‘Tracker’ software to investigate variation electromagnetic damping coefficient with distance between and This can indeed serve as valuable educational tool for undergraduate students, covering topics such damped oscillation, damping, Lenz’s law, eddy currents.
We determine the acceleration due to gravity [Formula: see text] in a novel way using magnetic sensor and video analysis technique of smartphone. The same applications are used measure terminal velocity magnet falling through conducting pipe moment from its torsional oscillations. This experiment would appear be intriguing, as it combines elements magnetism, velocity, electromagnetic damping text].
Determination of the Young modulus a metal bar in form cantilever is an old experimental concept. However, we have taken advantage modern advanced technology smartphone camera to find load depression graph by taking photographs with camera. Smartphone photography allows us precise transverse magnification object from size real image formed on sensor Image can be obtained micron level accuracy. From graph, determined bar. The sensitive measurements at its free end own weight, allowed...
