Geez, they're expensive nowadays. I still have mine.
** I once acquired a demagnetiser that, far as I could tell, was incapable of demagnetising anything.
Had no effect on tape heads or the tiniest screwdrivers. It was the Teac E1 as listed in your link.
So acting on a hunch, I made a coil of enamel wire ( about 15 turns) just big enough to slip over the head concerned and energised it from a small 6.3V tranny. The coil would get quite hot in about 30 seconds.
While energised, I popped it over the head and slowly removed it far away.
Totally worked on even the most magnetised heads.
