Question 3:9 points Earth's Magnetic Field: The following data were recorded from the horizontal component of earth's magnetic field R: radius of the coil. N: Number of turns experiments....
Data Table One Angle of Inclination ( ф ) Deflection current (l45) - L-60- 201.5mA Turn on the power supply and adjust the fine voltage settings until the needle of the compass in the galvanometer is deflected by exactly 45 degrees from north. Use the DMM to determine the circuit current. Record this in Data Table One. Q1: The Biot-Savart integral gives the magnetic field at the center of a closed circle. The tangent galvanometer coils have 20 turns and...
instrum.. x May 20, าร Question 3 The coil of a moving coil galvanometer (used in strip chart recorder) has 40 000 turns and is suspended in a uniform magnetic field of 0.18T. The control constant is 0.CISN-m per radian. The coil is 60mm wide and 30mm high with a momeni of inertia of 0.005 kg-m The damping constant is 0.014 N-m per radian per second and the coulomb friction is 0.13 x10 N.m. Determine e current required in the...
