11. She was born in Aarhus and raised in the Oersted Djursland, about 14 miles from Randers. 12. 1820-Danish physicist Hans Christian Oersted announces his discovery that an electrical current creates a magnetic field. 13. Coercivity is usually measured in oersted or ampere / meter units and is denoted " H" 14. To the northwest, the flooded crater Oersted P is attached to the northwest arm of the outer rim. 15. The 8050 and 8250 did not write with enough power to use 600-oersted PC high density disks reliably. 16. The oersted is 1000 / 4? ( H " 79.5774715 ) amperes per meter, in terms of SI units. 17. The oersted is closely related to the permeability \ mu r ( relative to permeability of vacuum ), their relation is: 18. Just to the south is a younger, still-intact crater named Oersted A that was formed after Oersted was flooded. 19. Just to the south is a younger, still-intact crater named Oersted A that was formed after Oersted was flooded. 20. The use of permalloy for the magnetic and silver for the non-magnetic layers lowered the saturation field to tens of oersteds .
