What exactly are Hall Effect Sensors? How exactly are they useful in a Maglev Train Model?

Okay, I am totally into electrodynamics stuff eversince i got introduced to the topic few months back. I gotta do something for my K12 project and i thought i could do Maglev. As far as I've understood, there are two major methods of building a model maglev - 1. the superconductor method 2. the linear motor method. The superconductor method is way too expensive for a school project so i am left with the Linear Motor method. Now, there are many kids in my school who have done Maglev that work mechanically (by giving an push the train kinda runs), the easiest and the cheapest way to make a train. So mine's gotta be the higher end one. So mine will be an 'automatic' (powered by cells) model, and also intelligent to some extent. So i searched books and the internet and i found this extremely common method to do it - it requires this this device called as 'Hall Effect Sensor". Will be glad if someone tells all about this thing. Thanks a ton in advance!!
