The MagnetiSiM around the world series

Making SENSE of your SENSORS

The Hall effect sensor competition!

Join the MagnetiSiM 2023: Making SENSE of your SENSORS competition with the IEEE Students in Magnetism! Design and build a fun project demonstrating the use of Hall effect sensors in a creative device or a tool for everyday use.


In 1879, Edwin Hall discovered the Hall effect.

In his experiment, he placed a strip of conducting material in between magnet poles with the magnetic field lines being perpendicular to the strip surface plane.

Hall observed that there is a voltage developed perpendicular to the current flowing direction and concluded that the magnetic field exerted forces on the flowing electric charge.

Hall sensor competition guidelines


Category 1: Pre-university students, high school students

Category 2: Undergraduate students, graduate students

  • Participants are allowed to take part in the competition as an individual or as teams of up to two members.


The primary objective is to provide an opportunity for students to explore the potential of hall effect sensors in various applications. This competition also aims to encourage students to showcase their creativity and innovation by utilizing Hall effect sensors in their projects.


  • The project must utilize at least one Hall effect sensor in the setup - introductory materials to the Hall sensor are available here

  • The results of the product’s effectiveness and demonstrative abilities must be documented and included in the submission package. 

  • Be creative, innovative, and savvy!

Submission Package

  1. A 2-4 pages concise report that includes

    (i)   the parts and components that were utilized,

    (ii)  expenses of the project, and

    (iii) step-by-step instructions to explain the setup.

    Participants are highly encouraged to submit accompanying photos to support the report. 

  2. A creative video of maximum 7 minutes, that showcases the final project and its effectiveness in demonstrating the Hall effect sensor’s versatility. 


Submission platform will be launched soon.

How to apply

  1. All participating individuals and groups are required to fill up this application form (one form per group)

  2. Participating groups of under the age of 18 years old are required to appoint a teacher as the project mentor. A letter from the project mentor indicating agreement to supervise the project (with the students being mainly responsible for doing the work).

  3. Application period is open till 1 October 2023

  4. Participating individuals and groups are open to either fund their own parts or apply for funding to obtain a basic starter kit

Funding application

  1. IEEE Students in Magnetism will fund a basic electronics starter kit and Hall sensor(s) per group

  2. Funding is subjected to approval, with the submission of a project proposal (one proposal submission per group) through the following proposal submission form

  3. Funding will be given out on a first come first served basis, subject to availability - the organizers encourage participating individuals and groups who are interested in applying for the kit to submit their proposal as soon as possible. 

  4. Kits will be purchased and delivered to the participating individuals and groups whose proposals are approved

  5. Proposal reviews will take approximately seven working days. 

  6. Project funding requests will cease on 1 September 2023
