## 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

T

_{max}= AIB

T

_{max}= I(0.03)(0.02)(2)

T

_{max}= 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...
