SUMMARY
The magnetic field at point P in a current loop can be calculated using the formula B=√2μ0i/8pia, where μ0 represents the permeability of free space, i is the current, and a is the length of the conductor. In part b of the problem, the contributions from the sections of the wire where the current is directed toward or away from point P do not affect the magnetic field due to the cross product being zero. The total magnetic field at point P is determined by summing the contributions from the remaining wire sections, taking into account their geometrical similarities and the inverse square relationship of the magnetic field strength.
