About this Mod

As of the 1st of June 2025, all future updates for ampz mods will require Voltaic API, and not Electrodynamics, in order to function. This update affects all the mods and brings world breaking changes, which are written in the changelogs. Note that this should however not corrupt your world. If you have such issues reach out on our discord channel!
Electrodynamics is a mod that brings realistic, world-based science and technology into Minecraft, along with some other additions. Electrodynamics intends to be realistic but still an enjoyable mod.
The mod serves as the core component of several other mods aiming to recreate the old Voltz-modpack, such as Nuclear Science, MFFS, ICBM, and others.
**
This project is based upon Voltaic and requires this mod to run. **

Electrodynamics server crashes on startup – what to do?

Server lagging with Electrodynamics – how to optimize performance?
Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Electrodynamics consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
