Query: Magnetic Flux Cancellation in Ellerman Bombs   Ellerman Bombs (EBs) are often found co-spatial with bipolar photospheric
magnetic fields. We use H$\alpha$ imaging spectroscopy along with Fe I 6302.5
\AA\ spectro-polarimetry from the Swedish 1-m Solar Telescope (SST), combined
with data from the Solar Dynamic Observatory (SDO) to study EBs and the
evolution of the local magnetic fields at EB locations. The EBs are found via
an EB detection and tracking algorithm. We find, using NICOLE inversions of the
spectro-polarimetric data, that on average (3.43 $\pm$ 0.49) x 10$^{24}$ ergs
of stored magnetic energy disappears from the bipolar region during the EBs
burning. The inversions also show flux cancellation rates of 10$^{14}$ -
10$^{15}$ Mx s$^{-1}$, and temperature enhancements of 200 K at the detection
footpoints. We investigate near-simultaneous flaring of EBs due to co-temporal
flux emergence from a sunspot, which shows a decrease in transverse velocity
when interacting with an existing, stationary area of opposite polarity
magnetic flux and the EBs are formed. We also show that these EBs can get
fueled further by additional, faster moving, negative magnetic flux regions.
