Answer 3

\(\vec F\)=\(I\vec L\) X\(\vec B\)

Answer 4

ans: D

Answer 5

force is proportional to both currents

Answer 6

if i Increased I1 by 5 and i2 is increased 2 time...the force will be 10times?

Answer 7

yes

Answer 8

i Just want to verify something...
if the currents are traveling in opposite direction, they will attract each other?
if the are in the same direction, they will repel?

Answer 9

yes

Answer 10

@roadjester what is b?

Answer 11

magnetic field
