Question

A rectangular loop has 85 turns with an area of 0.225 m2 and lies in a uniform magnetic field of 0.28 T. Several Physics lab students have reported that the greatest torque exerted on this loop is 1.2 × 10-2 Nm.

(i) What is current in the coil?

(ii) If instead, all 85 turns are unwound and form a rectangle with the same shape (but obviously much larger), would value of the current be LARGER, SMALLER, or THE SAME?

(iii) Compute the value of the current in this case to confirm your answer above.
