The net magnetic flux at the surface is about 3 kG.
I've never seen such a powerful magnetic flux artificially generated.
This quantity is the absolute value of the magnetic flux.
Changing the current in the primary coil changes the magnetic flux that is developed.
Up to now a current appeared to be absolutely essential for creating a magnetic flux.
The change of the magnetic flux in time outside a conductor is zero.
"The magnetic fluxes have been a lot worse in the past couple months."
At the gap, the magnetic flux forms a fringe pattern.
Spock would have been able to tell him exactly how much magnetic flux was being generated.
But the magnetic flux couldn't be measured, which told them something about the magnitude of the power they could tap.
