Answer:
Unlike the mineral-rich crust and mantle, the core is made almost entirely of metal—specifically, iron and nickel. The shorthand used for the core's iron-nickel alloys is simply the elements' chemical symbols—NiFe. Elements that dissolve in iron, called siderophiles, are also found in the core.

Answer:
(c) keeping the orientation of the loop fixed and moving it along the field lines
Explanation:
Ampere's Law current is calculated by evaluating;
∫ B. dl
Here B= magnetic field and dl- length segment in which current is to flow.
Clearly as magnate field lines are perpendicular to the plane of loop having some length ==> dot product will be zero for 90 ° angle and hence current will be zero in the loop i-e we will keep the position of loop and move it along field lines !
