Answer:
Olmec civilization began between 1400 and 1200 BCE, according to popular belief. Previous discoveries of Olmec bones ritually deposited at the shrine El Manat near the triple archaeological sites known as San Lorenzo Tenochtitlán pushed the date back to "at least" 1600–1500 BCE.

Answer:
0.957mm
Explanation:
The on-axis magnetic field of a current loop(B_loop) is is 4.9 nT
B_loop = (2μAI) / (4πz^3).
Where z is defied as distance from the current carrying loop,
A is the total enclosed area of the loop,
I is the current,
μ is the permeability constant (4π*10^-7).
4.9 nT = (2* 4π*10^-7 *A *32A) / (4π* (50cm)^3)
4.9 *10^-9 = 5.12*10^-5 A
A = 0.0000957 m
=0.957mm
