Amount of charge spherical conductor can hold in air

AI Thread Summary
The maximum charge a spherical conductor can hold in air is influenced by the breakdown voltage of air, which is approximately 3 million volts per meter. For a spherical conductor with a radius of 5.0 cm, the maximum charge can be calculated using the formula Q = 4πε₀rV, where V is the breakdown voltage. The air's role is crucial as it determines the voltage at which ionization occurs, leading to electrical discharge. Without a specified voltage, the calculation cannot be completed, but understanding air's breakdown properties is essential. Thus, the maximum charge depends on both the conductor's size and the electrical characteristics of the surrounding air.

I'm a little thrown off by this because we there is no voltage value given...
And how does the air play into the problem? I just something to help me get started:

What is the maximum amount of charge that a spherical conductor of radius 5.0 cm can hold in air?

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
