Interaction of a Current Loop with a Magnetic Field

Click For Summary
SUMMARY

The discussion centers on calculating the torque exerted on a current loop due to its interaction with a magnetic field. Given a current of 0.500 A and a magnetic field strength of 0.300 T, the torque about the vertical axis is derived using the equation for torque in a magnetic field. The initial position of the loop is at an angle of 30 degrees, leading to a calculated torque of 1.03 x 10^-8 N*m. The correct application of trigonometric functions is crucial for accurate results.

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

The Attempt at a Solution



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


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

Can anyone help me?
 
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.)
