Spark can jump among two non touching conductors

Reference no: EM13664064

A spark can jump among two non touching conductors is the potential dissimilarity is large. A potential dissimilarity of 940V is required to produce a spark in an air gap of 1.0x10^-4. Assume the light bulb in the figure is replaced by such a gap. How fast would a 1.23m rod have to be moving in an magnetic field of 6.47T to reason a spark to jump across the gap?
