I tried to document exactly how everything works via comments in the function files. Feel free to contact me with any questions.
Regular chainmail leggings are unaffected and can be used normally.
Teleports items to you in a 5 block radius.
- Only one item entity at a time is teleported on purpose, so you can't 'carry' multiple stacks of item entities with you as you move like you can with many modded magnets.
Makes all items in a 10 block radius play a quiet sound (in the "player" sound category) to help you find them.
- Plays a quieter, pitch shifted version of the Experience Bottle Thrown sound, if you have captions enabled.
- More item entities causes the sounds to stack and get louder.
When allMobs_Laggy is enabled, any mob wearing a magnet in its legs slot or primary hand slot will have the magnet effect applied. Tested with zombies, skeletons, zombie pigmen, foxes, and villagers.

I used an online tellraw generator to produce tellraw commands - those are a pain.
Multiple stackoverflow, reddit, and minecraft forums posts explaining command behavior and nitpicky syntax were read in the process of squashing bugs.
