Answer:
neutrons protons electrons
Explanation:
after the Big Bang, the universe was filled with neutrons, protons, electrons, anti-electrons, photons and neutrinos.
Magnetic field 'B' at a distance 'r' from an substantially
large conductor carrying current 'i' = (2x10^ -7)('i' ) / r
Magnetic field 'B' beyond the wire= (2x10^ -7)(8.15x10^18x1.6x10^ - 19 ) /0.046
=5.7 x10^ -12 tesla
As electrons move from west to east, the conventional current is from east to
west.
By means of Maxwell's right handed corkscrew rule, the way of magnetic field is
from south to north.
