Magnetic Permeability Comparator Kit with Arduino Uno + Sensor
Measure Magnetic Permeability of Iron, Aluminium & Air with This Arduino-Based Comparator Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Using a Hall effect sensor, you’ll measure magnetic flux density through different core materials — iron, aluminium, and air — and calculate relative permeability on a 16x2 LCD. The real-time clock stamps your data, which gets logged to microSD for analysis. It’s a complete measurement system that brings physics textbook concepts to life and reinforces the link between theory and hands‑on engineering.
What You'll Build
A tabletop instrument that reads magnetic flux via a Hall sensor, compares core materials, displays permeability results on an LCD, and logs time‑stamped data to a microSD card. By the end of the project, you’ll have a fully functional permeability comparator you can use for school projects, science fairs, or university lab work — no extra modules needed.
What You'll Learn
- Calibrating a Hall effect sensor to measure magnetic flux density precisely
- Computing relative permeability from raw sensor readings and applying it to different core materials
- Interfacing an I2C LCD and a DS3231 real‑time clock with Arduino for display and timestamping
- Logging sensor data to a microSD card and exporting it for analysis in any spreadsheet tool

Who This Kit Is For
CBSE Class 11–12 students exploring magnetic properties for physics practicals, B.Tech ECE/EEE first‑years wanting a hands‑on sensor project, Smart India Hackathon participants prototyping sensor‑based solutions, and ATL Tinkering Lab mentors seeking a fully documented kit for group activities will find this comparator straightforward to build and immensely educational.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to start a conversation with the AI companion, which has seen every wiring and code step for this kit. You can also message us on WhatsApp for real‑time human help.
What additional materials are needed to run the experiment?
You’ll need a small neodymium magnet and at least two core samples—iron and aluminium rods work great. These are standard in physics labs and are not included in the electronics kit.
Is this project suitable for a CBSE Class 12 physics investigatory project?
Yes, the experiment directly aligns with the magnetism unit. The logged data can be used for your practical file, viva, and project report.
Can I modify the code to compare more materials or change logging settings?
Absolutely. The AI companion can guide you through tweaking the Arduino sketch to add new materials, change log intervals, or export CSV data.
Hall sensor reads magnetic flux through iron, aluminium and air cores. Compares relative permeability.
