If you know the maximum and minimum currents in the two buss bars and their polarity, you can subtract the minimum from the maximum and use that resultant to size the magnetic circuit.

Maybe this will help to get a feeling of the distances involved.
That 1 part in 9 billion is the rough equivalent of walking around the Earth 375,000 times versus 375,001 times 375,000 times plus 1 mile.

When I am going someplace unusual, I usually have my wife and her tablet or cell phone along. (they are decent navigators between them)

Kyoto University scientists mass-generate cells for sperm, eggs using human iPS
The research, published in the online edition of the British science journal Nature on Monday, amplified the number of male and female primitive germ cells over 10 billion times from their initial culture stage...
I'm wondering if the popularity of Password Security Software is based on angst, personal insecurity, corporate decrees, or actual need... as perhaps national security reasons.
A FIrewall/Virus Scanner/Sandbox approach is quite protective... and A LOT less intrusive!
Yea, it does.
Ultimately, there needs to be either a manually operated clutch somewhere in the drivetrain, or any braking action within the motor/drivetrain be disabled.
The only possibility I see for a clutch is something that moves axially to disengage.
Think the starter on your car, or the...

A side note:
As a kid, we would occassionally play 'sand lot' baseball. One day I was pitching to a very good hitter.
Normally when pitching I would release the ball by releasing my thumb pressure. This would impart a little spin to the ball as it left my hand/fingers. One day I tried...
