A beam of protons traveling at 1.20 km/s enters a uniform magnetic field, traveling perpendicular to the field. The beam exits the magnetic field, leaving the field in a direction perpendicular to its original direction (the figure ( Figure 1)). The beam travels a distance of 1.20 cm while in the field. Figure 1 of 1 Part A What is the magnitude of the magnetic field? Express your answer in teslas. B = Submit Request Answer
