Because when people first discovered these lodestones, or they took a lodestone and they magnetized a needle with that lodestone, and then that needle they put on a cork in a bucket of water, and that needle would point to the

Lock tape drive on mount

Eject tape on unmount

And these tin particles were deposited on the tape heads and were crashing the tape heads.

The south pole of my magnet here is going to be attracted to Earth's magnetic south.

But with magnetism you always have a dipole.

This is an MRI MRA MRV, a volumetric MRI.

But how many fluxons, how many magnetic strands are there in a single disk like this?

Magnetic north is the geographic location, where the north pole of a magnet will point to.

Magnetism always comes in the form of a dipole.

Try to eject the tape after it has been unmounted. This option should not be used for floppy tape drives.

So if this side of my magnet is attracted to Earth's north pole then Earth's north pole or Earth's magnetic north actually must be the south pole of that magnet.

Tape ID on tape does not match tape ID in index file.

Tape is still mounted. The index for a mounted tape cannot be deleted. Unmount the tape and try again.

Or another way to put it, if we have a magnet, the direction of the magnet or the side of the magnet that orients itself if it's allowed to orient freely without friction towards our geographic north, we call that the north pole.

So what it actually does, it locks these strands, which are called fluxons, and it locks these fluxons in place.

It doesn't emit in the electromagnetic spectrum. It doesn't reflect.

So if this is a magnet, and let me draw another magnet.

No tape index is selected. In order to delete a tape index, the tape index to be deleted must be selected in the tree first.
