I think it is a mistake to refer to magnetic field 'flowing. Magnetic fields just are, they can change, and these disturbances might move in space, but the field itself does not flow.
That being said, and assuming you meant to ask in which direction a magnetic field points the answer is that a magnetic field points towards the south pole of a magnet and away from the north pole. A magnetic field cannot be divergent (i.e. there are no sources) and any field line must be closed.

How could you change the direction in which a compass needle points using a cell and a piece of wire?
The compass will react to magnetic fields, and magnetic fields are caused by currents. Therefore, holding a current-carrying wire close to the compass is enough to change the direction in which it points.The compass will react to magnetic fields, and magnetic fields are caused by currents.

If you made another compass with the same materials would the needle point be in the same direction?
the needle points in the direction the magnetic fields wish. The gravity pulls the compass nearer and nearer the magnetic fields.
The direction of a magnetic field produced by an electric current depends on the direction of the what?
Flow of the current.
What are 2 ex. of how electricity and magnetism are interrelated?
First of all, the concepts of both magnetism andelectricity involve fields. An electric field is caused by a point source charge (which is + or - in charge) and is characterized by field lines emanating from the point source charge. Magnetic fields are similar, but are actually caused by charges in motion. Another instance of the interrelatedness between the two phenomena is that the magnetic field is perpendicular to the electric field. Finally, electric fields can cause a current to flow through a wire. As a result of the flow of current, A potential difference is created (voltage) and a magnetic field is formed encircling the length of the wire. The direction of the magnetic field (clockwise or counterclockwise) depends on the direction of current flow.
How do the electric and magnetic field of an electromagnetic wave regenerate each other?
No. Current flow creates electromagnetic fields in space. Electromagnetic fields, in turn, can create current flow in conductors. The electric fields do not directly create magnetic fields, nor do magnetic fields directly create electric fields.
What type of fields are created by an arrangement of electric charges or a current?
Magnetic fields can be created by charges or the flow of current.
What fields gravational magnetic or electric can only exist in one direction?
gravitational
What additional factor will be change if the direction of a current flow is change?
direction of magnetic field
Is a magnetic domain a group of atoms whos magnetic fields are alinged in a common direction?
Yes, that's the basic idea.
How will magnetic minerals align in a rock if earth has no magnetic field?
Assuming there is no Earth magnetic field, and no other significant magnetic fields, they will not allign in any preferred direction.
Does current affect electromagnetism?
Does current affect electromagnetism? No. Does current affect magnetic fields? Yes. The laws (Maxwell's Equations) pertaining to electromagnetism is constant and will not change regardless of current applied. However, Maxwell's equations does dictate that a change in current will essentially result in a change in magnetic fields. Current flow will produce a magnetic field perpendicular to the current direction.
How does a tangent at any point on the magnetic field line show the direction of magnetic field at that point?
This is true for any contiguous function, not just magnetic fields.
