Solve a problem differing from the foregoing one by a magnetic field with induction \(B=0.8 \mathrm{~T}\) replacing the electric field.
3.368. (a) \(E^{\prime}=\frac{\beta B \sin \alpha}{c \sqrt{1-\beta^{2}}}=1.4 \mathrm{nV} / \mathrm{m}\); (b) \(B^{\prime}=B \sqrt{\frac{1-\beta^{2} \cos ^{2} \alpha}{1-\beta^{2}}}=0.9 \mathrm{~T}, \alpha^{\prime} \approx 51^{\circ}\)
