Mob Magnetism
by Brutox
Mob Magnetism is a Fabric mod for 1.21.1 that lets players pull, push and collide mobs using magnetic charges held in a handheld device.
What it does
Players hold Sneak and throw a magnetic tag, a compact handheld gadget with a default-sized hand model, and the tag sticks to the ground where it lands. Left-clicking a mob tags it with a positive charge, right-clicking tags it with a negative charge, and a tag can be placed on many mobs at once. Activating the device pulls nearby mobs toward its center within a 20-block radius. Opposite charges slam together with a collision and fly apart, while matching charges repel each other.
Mobs caught in a collision can die in a safe, non-destructive explosion that does not break blocks. A separate Implosion Grenade is throwable like a splash potion and uses the same charge system. The current 1.1.3 release replaces the earlier glove models with a sci-fi weapon system, called the Polarity Core, that uses its own 3D model. The items sit in the Combat Tools and Utilities tabs of the Creative Inventory.
Mob Magnetism runs on client and server, so both the server and every player need it. Only the 1.21.1 game version is supported, and the latest Fabric file is 1.1.3 for 1.21.1, published 2026-06-16. The code is open source under the MIT License.
Key features
Charge tagging
Left-clicking a mob applies a positive charge and right-clicking applies a negative charge, with a particle effect that shows the polarity.
Area pull and repel
The device pulls mobs within a 20-block radius toward its center, and matching charges push them away from each other.
Implosion Grenade
A throwable grenade with its own 3D model that works like a splash potion and triggers the same charge collisions.
Non-destructive explosions
Mobs that collide in a charged explosion can die without the blast breaking any blocks around them.

How it compares
Magnetism mod is also Fabric for 1.21, client and server, open source under the MIT License, but it targets the older version. Magnetic Mining is a Fabric and NeoForge mod for 26.2 – 26.3 under All rights reserved, so it is not open source. Magnetic Players is server-side only for 1.21.1 – 1.21.5, under the GNU General Public License v3.0 or later, and players join without installing it.

🧲 MOB MAGNETISM — NEW UPDATE! This is a physics based mod that made entirely for pure fun. Hey everyone, welcome back! Version 1.1.3 completely overhauls the mod. We threw out the old glove models and replaced them with a brand-new, clean sci-fi weapon system featuring custom 3D models and automated physics.
