Short Answer

Repeat Exercise 22.41 but with the loop lying flat on the ground with its current circulating counterclockwise (when viewed from above) in a location where the Earth's field is north, but at an angle $45 °$ below the horizontal and with a strength of $6.00 \times 10^{‐ 5} T$ .

(a) Maximum torque on a loop is $0.67 N ‐ m$ and direction is west.

(b) The torque is very small so the loop will not have any practical application as a motor.

Step 1: Definition of torque

Torque, also known as force moment, is the tendency of a force to spin the body to which it is applied in physics.

We can use the equation to determine the torque,

$τ = NIABsin (θ)$ ………….(1)

Step 2: Finding the torque using the formula(a)

Substitute the values in the equation (1), and we get

$τ = 200 \times 100 A \times 0.79 m^{2} (6.00 \times 10^{‐ 5} T) \times \sin (45 °) = 0.67 N ‐ m$

Hence, the required maximum torque on a loop is $0.67 N ‐ m$

Considering direction of force and current we find that the direction of torque is in west.

Step 3: Justification (b)

The torque is very small so the loop will not have any practical application as a motor.
