Homework Statement
You have a loop of wire (dimensions c and d) which is oriented vertically on the y-axis (the y-axis splits the rectangle in two equal pieces), and rotates about the y-axis at constant angular ##\omega##. The magnetic field is in the +i direction.
What would be the torqque needed to have the loop rotate at a constant w?
Homework Equations
##\tau = NIAB\sin\theta##The Attempt at a Solution
##\mathcal{E} = B(cd)\omega \sin( \omega t )## from Faraday's law.
##I = \dfrac{B(cd)\omega\sin (\omega t)}{R}##
I am not sure how to proceed from here...what do I set the torque, ##\tau = NIAB\sin\theta## equal to?
