QUESTION 5 A angular coil of wire H 24 c n by L-34 c and car yng a cu ent of 1.6 A İs one ted with the plane of its loop pe pendicular to a uniform 1.6 T magnetic field as shown in the figure. The coil is then rotated through a 28° angle into the plane. Calculate the torque that the magnetic field exerts on the coil. Hint: In order to help visualize this three-dimensional problem, make a the coil as viewed along the rotation axis.) (Give your answer in scientific notation using "'N.m" (Newton meter) as unit) out of the plane of the figure and the right side going careful drawing of Axis 0.09N.m QUESTION 6 A coil with magnetic moment 1.36 A.m2 is oriented initially with its magnctic moment antiparallel to a uniform 0.808 T magnetic field. What is the change in potential energy of the coil when it is rotated 180° so that its magnetic moment is parallel to the field? (Give your answer in decimal using sign) (Doule) as unit. Attention to the a QUESTION 7 A beam of protons traveling at 1.26 km/s enters a uniform magnetic field, traveling perpendicular to the field. The beam exits the magnetic field, leaving the field ina direction perpendicular to its original direction (see figure below). The beam travels a distance of 1.01 em while in the field. What is the magnitude of the magnetic field? (Give your answer in decimal using "mT" (milli Tesla) as unit) QUESTION 8 An electron in the beam of a TV picture tube is accelerated by a potential difference of 1.3 kV. Then it passes through a region of transverse magnetic field, where it What is the magnitude of the magnetic field? (Give your answer in decimal using "mT (milli Tesla) as unit)
