PC2021: Intermediate results, Problem 1, week 6

NB! The final deadline for submitting solutions of Problem 1: 13th February, 23:59:59 GMT
By the end of the sixth week, there are 951 registered participants from 71 countries (the list of countries is given below). In total, 88 solutions were submitted, out of which 27 were correct.

For this problem, I have decided to consider a solution as deserving full marks even if the answer for 2MT-strong B-fields is incorrect, as long as the formula gives a correct answer for ca 10 times weaker fields. However, those of you who have a good answer for 2MT-strong B-fields, have better chances of getting the best solution award.
