question

The duration of a 90∘90^{\circ} or 180∘180^{\circ} pulse depends on the strength of the $\mathscr{B}_1$ field. If a 180∘180^{\circ} pulse requires 12.5μs12.5 \mu \mathrm{s}, what is the strength of the $\mathscr{B}_1$ field?
Plain-text mathematical notation (without MathML)
The duration of a 90^(∘) or 180^(∘) pulse depends on the strength of the $\mathscr{B}_1$ field. If a 180^(∘) pulse requires 12.5μs, what is the strength of the $\mathscr{B}_1$ field?
