Homework Statement
[/B]
A rectangular wire of length 3 cm and width 2 cm is suspended vertically between two poles producing a uniform field of 2 T. Calculate the maximum torque acting on the wire.
Homework Equations
Torque = AIB sin(Θ)
Maximum torque is when sin(Θ) = 1, so Maximum Torque = AIB
The Attempt at a Solution
Tmax = AIB
Tmax = I(0.03)(0.02)(2)
Tmax = 0.0012 I
Using the formula from the notes I feel like I can find the maximum torque in terms of the current I. Is there a way to obtain the torque without the current? I believe there is information missing in the question. All similar questions found on google or in the book always either give the current or give enough information to derive it. I haven't found a single such question without the current...
