Lorentz Force Calculator

Features
Read full description

Calculate the magnetic Lorentz force with precision and ease. Whether you're a physics student, engineer, or educator, this app gives you a powerful scientific calculator designed for electromagnetic force analysis. Key Features • Real-time Lorentz force calculation • Reverse solve for any variable • Unit conversion with dropdown menus • Interactive sliders for quick parameter adjustment • Scientific notation input and output • Calculation history • Tap-to-copy results • No account required, no ads, fully offline Powerful Formula Engine Compute F = qvB sin(θ) instantly. Enter charge, velocity, magnetic field strength, and angle to get the resulting force in real time. Need to find a different variable? Toggle Reverse Solve mode to calculate any unknown — charge, velocity, magnetic field, or angle — from the remaining known values. Flexible Unit System Work in the units you prefer. Choose from Newtons, millinewtons, micronewtons, or kilonewtons for force. Select Coulombs, elementary charge (e), or nano/micro/millicoulombs for charge. Velocity supports m/s, km/s, km/h, and the speed of light (c). Magnetic field options include Tesla, millitesla, microtesla, and Gauss. All conversions are handled automatically. Calculation History Save important calculations and revisit them anytime. Tap any saved entry to restore all input values and units instantly. Manage your history with swipe-to-delete or clear all. Designed for Learning Formula cards show the active equation and update dynamically when you switch solve modes. The Reference page provides a complete overview of all variables, physical constants, supported units, and example scenarios including electron deflection in CRT tubes and proton motion in cyclotrons. Built for iPhone and iPad The interface adapts to any screen size with a clean scrollable layout on iPhone and an optimized view on iPad. Full dark mode support ensures comfortable use in any environment. Tap any result to copy it to your clipboard. In physics, particularly in electromagnetism, the Lorentz force is the combination of electric and magnetic forces on a point charge due to electromagnetic fields. A particle of charge q moving with velocity v in the presence of an electric field E and a magnetic field B experiences a force. The Lorentz force is the force applied on a charged particle moving with velocity v perpendicularly into a magnetic field. A positively charged particle will be accelerated in the same direction as the electric field E, but will curve perpendicularly to both the instantaneous velocity vector v and the magnetic field B according to the right-hand rule. Lorentz Force Equation: F = q v B sin(α) Where: q - Particle's charge v - Particle's velocity B - Strength of the magnetic field α - Angle between the direction of the particle's trajectory and the direction of the magnetic field F - Resulting force Thank you for your support.

Verdict

The call

The clearest difference is price: Food Origin at Free against Lorentz Force Calculator's $2.99. Food Origin also leads on update cadence (fortnightly vs every 26 months) and iOS requirement (7.0 vs 17.6). On ads, in-app purchases and device support there is nothing between them.
