NESA Physics The Motor Effect

This value is too small. The calculated magnetic field strength is approximately $0.015 \text{ T}$, which is two orders of magnitude larger than $10^{-4} \text{ T}$.

Comparing the experimental relationship $F = 0.0306 \sin \theta$ to the theoretical formula $F = ILB \sin \theta$, we see that $ILB = 0.0306$. Solving for $B$ gives $B = \frac{0.0306}{2.4 \times 0.85} \approx 0.015 \text{ T}$, which is on the order of $10^{-2} \text{ T}$.

This value is significantly larger than the actual magnetic field. The calculation yields $B \approx 0.015 \text{ T}$, whereas $10^2 \text{ T}$ represents an extremely strong magnetic field not supported by the data.

This value is far too large. The calculated field strength is approximately $1.5 \times 10^{-2} \text{ T}$, which is six orders of magnitude smaller than $10^4 \text{ T}$.
