Smart Vibration Meter・Detector vs Magnetic Field Calc +

Vibration Meter is a free app that can measure the vibration (seismograph, body tremor, seismometer). This app uses phone sensors to measure vibration or the earthquake, and it shows a reference as a seismic detector. Using this app, you can check vibrations both on the Richter scale and on the modified Mercalli intensity scale. To calibrate application click on the button - Calibrate, put your device on the flat surface and wait till value stabilize. It should take about 20 seconds. After that click OK button and enjoy the earthquake! App shows reference to earthquake vibrations as classified by internationally used Mercalli intensity scale for seismic activities such as earthquakes. The Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. It measures the effects of an earthquake. Vibration Meter can also be called seismograph or seismometer when used for measuring seismic activity. Mercalli intensity scale: I. Instrumental - Not felt. Recorded by seismographs. II. Weak - Felt only on top floors of high buildings. III. Slight - Felt indoors, like a passing light truck. IV. Moderate - Windows, doors rattle. Like passing train. V. Rather Strong - Felt by all. Small objects upset. VI. Strong - Books off shelves. Trees shake. Damage. VII. Very Strong - Difficult to stand. Buildings damaged. VIII. Destructive - Significant damage. Trees broken. IX. Violent - General panic. Serious damage. Cracks. X. Intense - Most buildings destroyed. Rails bent. XI. Extreme - Rails bent greatly. Pipelines destroyed. XII. Catastrophic - Near total damage. Some countries use Richter scale instead of Mercalli scale. The Richter scale is a base-10 logarithmic scale, which defines magnitude as the logarithm of the ratio of the amplitude of the seismic waves to an arbitrary, minor amplitude.

Calculate magnetic fields generated by electric currents with precision and ease. Magnetic Field Calculator is a fast, offline physics tool designed for students, engineers, and science enthusiasts. FOUR CALCULATION MODES • Straight Wire — B = (μ₀ · I) / (2π · r) • Circular Loop — B = (μ₀ · I) / (2 · R) • Solenoid — B = μ₀ · n · I • Toroid — B = (μ₀ · N · I) / (2π · r) SOLVE FOR ANY VARIABLE Not just magnetic field strength — reverse-calculate current (I), distance (r), radius (R), turn density (n), or total turns (N). Select what you want to solve, enter the known values, and get instant results. INTERACTIVE DIAGRAMS Each mode displays a clear 2D diagram showing the wire geometry, field direction, and key variables. Visual learning made simple. FLEXIBLE UNIT SUPPORT • Current: Ampere (A), Milliampere (mA) • Distance: Meter (m), Centimeter (cm), Millimeter (mm) • Magnetic Field: Tesla (T), Microtesla (µT), Gauss All conversions handled automatically with high-precision SI calculations. BUILT-IN REFERENCE Quick-access formula sheet with constants (μ₀), formulas, variable definitions, and unit conversion tables — everything you need in one place. SAVE & REVIEW Save calculations to history for quick reference. Copy results to clipboard with one tap. WORKS OFFLINE No internet connection required. All calculations run locally on your device — fast, private, and reliable. Perfect for physics homework, exam preparation, lab work, electrical engineering projects, or anyone curious about electromagnetism. The magnetic force on a current-carrying wire is perpendicular to both the wire and the magnetic field, with the direction given by the right-hand rule. Magnetic fields arise from charges, similar to electric fields, but are different in that the charges must be moving. A long straight wire carrying a current is the simplest example of a moving charge that generates a magnetic field. The force a charge feels when moving through a magnetic field depends on the right-hand rule. The direction of the magnetic field due to moving charges also depends on the right-hand rule. The direction of the magnetic field is perpendicular to the wire and is in the direction the fingers of the right hand would curl if wrapped around the wire with the thumb in the direction of the current. The strength of the magnetic field depends on the current I in the wire and d, the distance from the wire.
