GEOLOGY

Detailed explanation-1: -The magnitude of o depends on three factors: the valence of the metal, the principal quantum number of the metal (and thus its location in the periodic table), and the nature of the ligand(s).

Detailed explanation-2: -The factors affecting the strength of a magnetic field at a point due to a straight current-carrying conductor are the magnitude of the electric current and the perpendicular distance between the point and the conductor.

Detailed explanation-3: -Magnetic strength of the core in the coil of wire. (stronger–> bigger emf) Number of turns of wire in the coil (more turns–> bigger emf) The cross-sectional area of the coil (bigger area–> bigger emf). How fast you move the magnet into/out of the coil.

Detailed explanation-4: -The strength of the external magnetic field. The force is proportional to the magnetic field strength, The magnitude of the current in the conductor. The length of the conductor in the field. The angle between the conductor and the external magnetic field.
