A current carrying semiconductor of thickness \(0.7\) mm is placed in a transverse magnetic field. The measured Hall voltage is \(0.9\) mV and the current is \(6\) mA. If the Hall coefficient is \(4 \times 10^{-4}\) \(\text{m}^3/\text{C}\), the value of the incident magnetic field is T (rounded off to two decimal places).
