Question 5 8 pts A rectangular coil consists of N = 40 closely wrapped turns and has dimensions ab = 2.12m and bc Z = 2.73m. The coil is hinged along the z axis, and its plane makes an angle 0=54.9" with the x axis. There 0 D is a current I=1.88A along the direction form a to b running through the loop, and a uniform magnetic field B = 0.57T directed along the x axis. Calculate the magnitude of the torque (unit in Nm) exerted on 3D View 2D View (z out of page) the coil by a uniform magnetic field. Question 6 7 pts A rectangular coil consists of N = 200 closely wrapped turns and has dimensions ab = 3.15m and Z bc = 2.56m. The coil is hinged along the z axis, and its plane makes an angle 0=350 with the x axis. There is a current I=4.25A along the direction form a to b running through the loop, and a uniform magnetic field B = 0.750T directed along the x axis. What is the expected direction of rotation of the coil 3D View 2D View (z out of page ) in the 2D view picture? O Counter clockwise O Clockwise O out of the page O into the pageQuestion 7 10 pts A Hall-effect probe operates with a 186mA current. When the probe is placed in a uniform magnetic field of magnitude 88.7mT, it produces a Hall voltage of 0.63uV. When it is used to measure an unknown magnetic field, the Hall voltage is 0.52pV. Find is the magnitude of the unknown field (unit in mT)
