Screenshots

Touch, observe, understand

Place and drag charges and magnets or move a slider, and the field lines and currents respond in real time.

**Resonance: the current peaks**Waveforms, phasors and the resonance curve

**Nearly uniform inside a solenoid**Field lines just like a bar magnet

**Turns ratio sets the voltage**See V₂ = V₁·N₂/N₁ in the waveforms

Features

Built for learning

Hands-on

Tap to place charges and magnets, drag to move them, and change voltage, resistance or coil turns with sliders.

Explanations with formulas

Every screen explains the physics and formulas behind it, from Coulomb's law to electromagnetic waves.

Easy to read and use

Dark and light themes, landscape, iPad and tablets are all supported.

73 languages

English, Japanese, Chinese, Korean, Spanish, Arabic and 67 more. The app follows your device language automatically.

Pricing & ads

The app is free. There are no in-app purchases, subscriptions or paid unlocks.

A Pangle banner ad is shown at the bottom of the screen. On iOS, the App Tracking Transparency (ATT) prompt appears at launch, and ads are personalized only if you allow tracking. On Android, the app asks once whether ads may be personalized. Either choice can be changed later from "About" > "Ad settings".

Requirements: iPhone and iPad with iOS 15.0 or later; Android 7.0 (API 24) or later phones and tablets.
