5 3. 5. Capt. Janeway of the Federation starship Voyager consults with Chief Engineer B'Elanna Torres about the specifications of the antimatter containment device aboard her starship. In the antimatter containment device, anti-protons particles of the same mass as protons but having negative charge are moving in a 4.00-m-diameter circular path at a speed of 5.00 x 107 m/s. What is the strength of the magnetic field in this antimatter containment device? A 026T B. 052T C.013T D. 26T Magnetic Resonance Imaging (MRI) can be dangerous for patients with pacemak- ers, as the powerful magnets in an MRI machine can cause the devices to be damaged or malfunction. Suppose a cardiac patient with a pacemaker is being scanned for an MRI im- age. There is a 10.0-cm-long section of wire in the pacemaker that moves with a speed 10.0 cm/s in a direction perpendicular to the MRI machine's magnetic field. This motion causes a 20.0-mV Hall voltage to be induced. What is the magnetic field strength of the MRI machine? A 20T B.15T C.10T D. 05T How many turns are in a 25-cm solenoid that carries a current of 50.0A and experi- ences a magnetic field strength of 0.0628 T in its interior? Round up to the next whole number. A 125 B. 250 C. 500 D. 25
