There is a sharp distinction between ionic and covalent bonds when the geometric arrangements of atoms in compounds are considered. In essence, ionic bonding is nondirectional, whereas covalent bonding is directional.
Answer:
The current in the wire under the influence of the force is 216.033 A
Solution:
According to the question:
Length of the wire, l = 0.676 m

Magnetic field of the Earth, 
Forces experienced by the wire, 
Also, we know that the force in a magnetic field is given by:



I = 216.033 A
