This circle represents a wire running towards you. Using the right hand curl rule, in which direction is the magnetic field moving if the current is flowing at you?

The magnetic field is moving towards me.

The magnetic field is moving away from me.

The magnetic field is moving in a clockwise direction around the wire.

The magnetic field is moving in a counterclockwise direction around the wire.

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
