Electromagnetic Suspension (Active Maglev with PID Control)

Capstone Project

Embedded Systems | Control Theory | Arduino | Electronics

Project Overview

This capstone project demonstrates an active electromagnetic levitation system that suspends a steel bolt beneath an electromagnet using closed-loop PID (Proportional-Integral-Derivative) control. The system continuously measures the position of the levitating object and dynamically adjusts the magnetic field to maintain stable levitation in real time.

Project Objective

The objective was to design and build a stable magnetic levitation system capable of maintaining a constant air gap through continuous feedback control. The project combines principles from physics, mathematics, electronics, and embedded systems to demonstrate how real-time control can stabilise an inherently unstable system.

How It Works


An IR distance sensor continuously measures the position of the levitating steel bolt. The sensor data is processed by an Arduino UNO, where a PID control algorithm calculates the required correction. The Arduino regulates the current supplied to the electromagnet through a MOSFET driver circuit, continuously adjusting the magnetic force to maintain the desired levitation height. An LCD display provides real-time information on the target gap, measured distance, and PWM output.

Habit Management and Student Well-Being

Date: January – February 2025

Grade 9th

What Inspired Me to Explore This Topic?

As a high school student, I often observe how academic pressure, deadlines, and extracurricular commitments make it difficult for students to maintain healthy daily habits. Many students struggle with procrastination, irregular sleep schedules, poor time management, and a lack of balance between academics and personal well-being. This motivated me to investigate the relationship between habit management, productivity, and overall well-being among teenagers.

Project Overview

This research explores how poor time management and procrastination can disrupt essential habits such as sleeping, eating, exercising, and maintaining a healthy routine. Through surveys, interviews, literature review, and product analysis, I examined the challenges faced by high school students and evaluated potential solutions that could encourage positive behavioral change.

Based on the findings, I designed a physical habit-tracking system aimed at helping students build consistency, improve self-discipline, and develop healthier daily routines through visual progress tracking and habit reinforcement.

Key Outcomes

  • Identified procrastination and poor time management as major barriers to habit formation among students.
  • Explored the impact of disrupted habits on mental well-being, stress levels, and academic performance.
  • Developed a habit-tracking solution that combines daily and long-term progress monitoring.
  • Applied principles of user-centered design to create an engaging, practical, and accessible tool for students.

Real-World Relevance

The challenges explored in this project are experienced by students worldwide. Research consistently shows that effective habit formation and time management contribute to improved academic performance, reduced stress, and better overall well-being. The concepts investigated in this project can be applied in schools, homes, and personal development programs to help students establish sustainable habits and achieve long-term goals.

Best Way To Design

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

First, solve the problem. Then write the code.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using ‘Content here, content here’, making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for ‘lorem ipsum’ will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

In some ways, programming is like painting. You start with a blank canvas and certain basic raw materials. You use a combination of science, art, and craft to determine what to do with them.

The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from “de Finibus Bonorum et Malorum” by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of “de Finibus Bonorum et Malorum” (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, “Lorem ipsum dolor sit amet..”, comes from a line in section 1.10.32.

Renewable Energy · Mechanical Design · Live Modelodel

Overview:

As part of my MYP Personal Project, I designed and built a working prototype of a Vertical Axis Wind Turbine (VAWT) a type of turbine where the main rotor shaft runs vertically, making it effective in capturing wind from any direction. Unlike a theoretical exercise, this project required me to physically construct, test, and troubleshoot a live functioning model, bringing together concepts from physics, mechanical design, and energy systems.

What I Did:

The project moved through three key phases initial concept development and planning, hands-on building and experimentation involving structure, wiring, and mechanical assembly, and finally a presentation where I explained the turbine’s function and design choices to evaluators. When early designs did not perform as expected, I had to revisit my approach, identify faults, and iterate experiencing firsthand that engineering is a process of continuous improvement rather than instant results.

Key Skills:
Mechanical Assembly · Renewable Energy Systems · Design Thinking · Problem Solving · Prototyping

Key Learning:

This project taught me that translating theoretical science into a working physical system requires patience, adaptability, and persistence. It deepened my interest in sustainable energy and mechanical design, and gave me confidence in tackling real engineering challenges. Most importantly, it showed me that the best learning happens when things don’t go according to plan and you have to find a way forward anyway.

F1 in Schools Engineering Design Exploration

Aerodynamics · CAD Design · Team Engineering

Overview:

During MYP Year 4, I participated in the F1 in Schools STEM programme organised by STEM Club India a global challenge that introduces students to engineering design through the creation of a miniature Formula 1 car. As a member of Team CO₂, I took on the role of Design & Manufacturing Team Member, using Autodesk Fusion 360 to develop and refine the car’s 3D model across multiple design iterations.

What I Did:

The design process began with an initial CAD concept focused on stability and competition specifications, before progressing through aerodynamic refinement smoothing curves, improving airflow, and optimising the front wing for reduced drag. Each iteration taught me how small design adjustments directly impact performance. Working within a team where members handled design, manufacturing, sponsorship, and presentation also gave me my first real experience of how engineering projects depend on coordination and shared problem-solving.

Key Skills:
