# Interaction of a Current Loop with a Magnetic Field

#### HELLO11

1. Homework Statement
Assume that the current flowing into the loop is 0.500A . If the magnitude of the magnetic field is 0.300 T, what is torque , the net torque about the vertical axis of the current loop due to the interaction of the current with the magnetic field?

the loop is initially positioned at (theta)=30 degrees

i know with the sin i have to subtract 90- theta

3. The Attempt at a Solution

When i plug in all the numbers correctly i get 1.03*10^-8

Can any one help me i am on my last try. The answer must be in N*m

Please provide the complete statement of the problem exactly as it was given. (A diagram would be helpful; lacking that, describe the direction of magnetic field compared to the orientation of the current loop.)
