A student compares two motor coils at the same position in the same magnetic field. The dimensions of every turn are identical. The table gives the measurements.
| Coil | Number of turns | Current / A\mathrm{A}A |
|---|---|---|
| P | 25 | 0.80 |
| Q | 40 | 0.30 |
The total turning effect is proportional to the number of turns multiplied by the current. What is the ratio of the turning effect of Q to that of P?
