7) I=8 L=0.1 F=75*10^-3 α=30 B=?
F=I*B*L*sinα B=F/(I*L*sinα)=75*10^-3/(8*0.1*0.5)=187.5 мТл
====================
8) I=15 B=50*10^-3 L=0.2 F=75*10^-3 α=?
sinα=F/(I*B*L)=75*10^-3/(15*50*0.2)=0.5 α=30°
===============
9) v=60*10^6 B=0.15 e=1.6*10^-19 F=?
F=e*B*v (sinα=1) F=1.6*10^-19*0.15*60*10^6=1.44*10^-12 H
