The Magnetizing Unit is required to charge and recharge shaft cores for use inside AC engines.

Rotarycraft Handbook DescriptionEdit

"The magnetizer uses a rapidly rotating shaft to create a magnetic field inside a shaft core. This is one of the critical components of an AC Electric Engine. It requires an AC redstone current and high speed."


Power 16.384 kW
Speed 2048 rad/s
Power Input Back
Other alternating redstone clock signal


Mousing over the shaft core in the interface will show accumulated charge in microTeslas.

Angular Transducer OutputEdit

Screwdriver UsageEdit

Right Click Rotate
Shift + Right Click

Duration of Operation FormulaEdit

Time(in ticks) = 400 - 20 × log₂ (speed + 1)

Max Shaft Core Charge Edit

Max Shaft Core Charge = Speed/2

Tips & TricksEdit

  • A 2-clock (1 tick on, 1 tick off) is the fastest and most efficient redstone clock to use with the Magnetizer.  Information on building a 2-clock can be found here (that site calls it a 1-clock)
  • If you are using vanilla redstone circuits, and the shaft core isn't charging even with enough speed and total power, remember vanilla minecraft redstone mechanics;  it's possible the clock signal isn't being transmitted to the magnetizer. Ensure that you make your redstone dust connections directly, approaching from a direction that is perpendicular to that of the magnetizer. That is, redstone dust will not make a connection if the final piece is placed in parallel with the magnetizer unit.
