of electromagnetism, communicated the news to Copenaghen the 21 July
1820 with one memory. The experiment of Oersted consisted in placing a
wire over a magnetic needle suspended,
parallel to
its axis, and these remain immovable, but when the thread is covered
from current electrical worker generated from a
battery,
the needle turns aside forming an angle of approximately 90
degrees, if the battery is sufficiently
powerful, if
the produced shunting line is weak person is smaller. Carrying the
thread under the magnetic needle, always covered from current
electrical worker, the shunting line is opposite to the previous
one. Concluded Oersted that the shunting line of the needle
was
due to the passage of the current electrical worker. In that
electromagnetism consists. | |
