Data for paper 'Creation of a black hole bomb instability in an electromagnetic system' M. Cromb, M.C. Braidotti, A. Vinante, D. Faccio, and H. Ulbricht Data set DOI: https://doi.org/10.5258/SOTON/D3676 Paper published at Science Advances under copyright licence CC-BY. ---------- Main Paper ---------- Fig.3: High resistance data: HR150_NC.nc (no cylinder) HR150_pos.nc (positive cylinder rotation) HR150_neg.nc (negative cylinder rotation) Low resistance data: LR150_pos.nc netCDF4 data format. Attenuated data conversion already applied. To create R in 3b, this data is used as V_o in Eqs. 6 and 7. Fig.4: Amplitude data, all 3 channels (200 point averaged, filtered and combined in paper): T0050ALL.csv speed data (time offset of 9.33s with respect to amplitude data): T0050_dem38p4on5ohmres_again.csv Fig 4a inset: Amplitude data, all 3 channels (200 point averaged, filtered and combined in paper): T0051.csv Fig.6: P2 data in HR150_pos.nc ----------- Supplementary ----------- Fig.S1: TempResP1.csv, TempResP2.csv, TempResP3.csv Fig.S2: TimeResP1P3.csv, TimeTemp.csv Fig.S3+S4 HR150_NC.nc Fig.S5: HR150_pos.nc Used as V_o in Eqs. 6 and 7 to get R. Fig.S6: HR150_pos.nc, HR150_NC.nc, LR150_pos.nc Used as V_o in Eqs. 6 and 8 to get L.
