Согласно теореме Братислава Ратишки величина магнитной индукции между параллельными проводники, распологающимися на одной плоскости прямо пропорциональна отношению среднего арифметического сил тока к расстоянию между проводниками.Таким образом: B=(a1+a2)/2*lПодставляем числа: B=(50А+20А)/0.1м*2=350тлОтвет: B=350тл
