Current Attempt in Progress A charged particle enters a uniform magnetic field and follows the circular path shown in the drawing. The particle's speed is 142 m/s, the magnitude of the magnetic field is 0.446 T, and the radius of the path is 714 m. Determine the mass of the particle, given that its charge has a magnitude of 7.42 x 10-4 C. I (out of paper) Number i Units VCurrent Attempt in Progress A long solenoid has a length of 0.58 m and contains 1500 turns of wire. There is a current of 7.8 A in the wire. What is the magnitude of the magnetic field within the solenoid? Number i UnitsCurrent Attempt in Progress The magnetic field produced by the solenoid in a magnetic resonance imaging (MRI) system designed for measurements on whole human bodies has a field strength of 8.61 T, and the current in the solenoid is 2.33 x 102 A. What is the number of turns per meter of length of the solenoid? Number i Units
