Electromagnetic Induction
by Anonymous · ⭐ 1 · 🍴 0
When a magnet moves toward or away from a coil, that motion alone creates a current. Change the magnet's speed to hit 2V and then 3V of induced EMF, raise the number of turns from 10 to 40 to measure how much the EMF grows for the very same motion, then flip the pole and the direction to watch Lenz's law at work — the induced current always opposes the change.
About this app
Electromagnetic Induction is an interactive high-school physics learning app about how a moving magnet produces voltage in a coil. Explore how magnet speed and the number of coil turns affect induced EMF, then use different magnet poles and motion directions to investigate the direction of induced current under Lenz’s law. Mission-based activities guide learners through target values and comparisons.
Use cases
- High-school students studying electromagnetic induction
- Teachers demonstrating Faraday’s law and Lenz’s law
- Learners practicing how speed affects induced EMF

Features
- Adjust magnet speed across stopped, slow, normal, and fast settings
- Observe induced EMF values on an interactive gauge
- Change coil turns, including values from 10 to 50
- Combine coil turns and magnet speed to reach target EMF values
- Switch between N and S poles and approaching or moving-away directions
- Compare clockwise and counterclockwise induced-current directions
