Homework Equations
FM in uniform magnetic field = I L x B
m = I A2 where A is the area, direction given by Right Hand Rule (perpendicular to plane of loop)
T = m x B
The Attempt at a Solution
I need to know if my answers are correct..need fast confirmation/help.
a) using the 1st equation in the "Relevant equations"
i added all forces and it equaled to zero. but I am not sure if the unit vectors with
1/ sqrt(2) should play a role in the calculation.. I just used the i hat and k hat without the 1 / sqrt(2).. is this ok?
or...am i supposed to factor out the 1 / sqrt(2) for the magnitude of B so it's like 1/sqrt(2)B0 ?
b) using 2nd equation in "Relevant Equations":
m = I0 a2 B0 k hat
c) T = a2 I0 B0 j hat
