Physics Toolbox Magnetometer vs Photronium

Measure, visualize, and record magnetic fields with precision — right from your iPhone. Physics Toolbox Magnetometer displays the magnetic field vector in x, y, and z dimensions along with total magnitude in microteslas (µT) or gauss, giving you the data you need for serious lab work or casual exploration. Three ways to view your data: - Chart — real-time graph with toggleable axes, adjustable line width, and fullscreen mode - Digital — large numeric readout for quick at-a-glance measurements - Compass — live heading with True North and Magnetic North display Built for the lab and the field: - Record and export data as CSV for analysis in other software - Adjustable sample rate from 1 to 100 Hz - Signal filters to reduce noise - Detects permanent magnets, electromagnetic fields, and background geomagnetic field Classroom-ready experiments: The magnetometer is well-suited for determining the inverse-square law for a point-source magnet, measuring the magnetic field produced by a solenoid, or capturing the periodic field variations of audio speakers and magnetic plate stirrers. Whether you are a physics student, teacher, engineer, or curious mind, Physics Toolbox Magnetometer turns your device into a capable scientific instrument.

With over 360 physics equations explained in a clear, easy-to-understand way and a flexible search system, Photronium can be an immensely helpful tool for learners of any level. PHYSICS AT YOUR FINGERTIPS Look up any physics equation, with topics including: • Motion in One Dimension • Projectile Motion • Laws of Motion • Uniform Circular Motion • Work and Energy • Linear Momentum and Collisions • Rotation of Rigid Bodies • Universal Gravitation • Fluid Mechanics • Oscillatory Motion • Wave Motion • Sound Waves • Thermodynamics • Electromagnetism • Light and Optics • Relativity • Quantum Physics All available offline, so you can learn anywhere, anytime. MEMORY QUIZ Test your knowledge by taking quizzes! Bookmark any section that interests you, and Photronium will automatically create quizzes based on those bookmarks. INTELLIGENT SEARCH & SYMBOL SEARCH Just type anything. Intelligent Search can work with the most ambiguous descriptions, like “atom”, “lens”, “radiation”, “Newton”, and “phase angle”. And when you need to find a physics formula without any description, Symbol Search provides a discovery experience you’ve never seen before. FREE & NO ADS Photronium comes with over 360 physics equations, Intelligent Search, Symbol Search, Widgets, Bookmarks, Suggested Websites, and Dark Mode all available for free and ad-free.
