Important history associated Nikola Tesla and it's his Birthday today.

Magnetic field strength. Would that be the same field strength measurement used to determine the strength of magnetically recorded data on hard disc drives etc?

Yes, the tesla is the SI unit of magnetic flux density and is named for Nikola Tesla. A particle carrying a charge of 1 coulomb passing through a magnetic field of 1 tesla at 1 meter per second experiences a force of 1 newton upon it. It is a bit large for normal use being equal to 10,000 gauss (the old CGS unit).

Something to raise at my next dinner party methinks.

Useful tip if the warning sign says "10 Tesla", step back. Actually, I'd keep backing up until you get to about 1 T.

It looks like hard drive degaussers are usually about 0.5 T.

I must confess I don't often get invited twice (unless my host slept through most of the dinner and can't remember) 😯

Even more strange is that there is a difference between the magetic flux (Weber or Maxwell) and the magnetic flux density.
