Short Answer

(a) What is the maximum torque on a 150-turn square loop of wire 18.0 cm on a side that carries a 50.0-A current in a 1.60-T field? (b) What is the torque when θ is 10.9º?

(a) The maximum torque is $360 N ‐ m$ .

(b) When $θ = 10.9 °$ , the torque equals $68.1 N ‐ m$ .

TABLE OF CONTENTS

Step 1: Definition of Torque.

Torque can be a force applied on the different current carrying loops/segments in a uniform magnetic field.

The torque can be estimated using the expression,

$τ = NIABsin (θ)$ ………………(1)

where the number of turns, $N$ , the current, $I$ , the area of the loop, $A$ , and the inclination angle of the loop, $θ$ .

Step 2: Finding the maximum torque(a)

The maximum torque can be obtained when $θ = 90 °$ .

The area of the current-carrying loop is,

$A = 0.18 m \times 0.18 m = 0.03 m^{2}$

This can be used in equation (1) to determine the torque, such that,

$π_{\max} = NIABsin (90 °) = 150 \times 50 A \times 0.03 m^{2} \times 1.60 T \times \sin (90 °) = 360 N ‐ m$

Therefore, the maximum torque is $360 N ‐ m$ .

Step 4: Finding the torque when the angle is (b)

Substitute the given data in equation (1), to determine the torque,

$π_{\max} = NIABsin (90 °) = 150 \times 50 A \times 0.03 m^{2} \times 1.60 T \times \sin (10.9 °) = 68.1 N ‐ m$

Hence, the value of torque is $68.1 N ‐ m$ .
