Answer:
The angle wires have to be placed to experience full force is such that the angle between the direction of current flow and the direction of the magnetic field is 90°
Explanation:
The direction of the force acting on a conductor through which a charge flows is given by Flemings Left Hand Rule which states that the direction of the force acting on a conductor carrying a current of charge is perpendicular to both the direction in which the current is flowing and the direction of the magnetic field
Therefore, wires carrying flowing charges has to be placed such that the direction of charge (current) flow is perpendicular (at 90°) to an existing magnetic field to experience (maximum) full force
Answer:
Isogonic line is a line joining the points of equal magnetic declination.
Explanation:
Isogonal line is a line that joins the places of equal declination. Also isogonal line is known as the line which connects the point having the same magnetic declination.

Scientists believe that on large scales the Universe is isotropic (the same in all directions). Thus, from our perspective, half of all spiral galaxies should spin clockwise, and half counter-clockwise.
