Investigation of Magnetic Fields by Search Coil

The method of splitting the phase of incoming power to produce a second phase of power, giving the motor enough displacement to start.

3. Along the axis of the coil and at the center of each compass needle starting 5 to the left of the coil, record the value of B. Move one compass needle to the right and record the value of B. Repeat until you’ve completed the table below. NOTE: Be sure to

The data amassed by the scientist revealed that the Mid- Atlantic Ridge and the East Pacific Rise and countless other locations on the ocean floors display the same arrangements of varying magnetic stripes. As new volcanic rock erupts through fractures on the floor of the ocean, a progression identified as seafloor spreading, which causes the seafloor to widen (Trefil & Hazen, 2010). This new rock will be pushed aside as the continents are moved apart and as more magma comes up to take its place. The iron ore in this latest rock will steer to the position of the magnetic north pole once they get through to the top. Every occasion, that the planet’s magnetic field moves in the opposing direction, the dipole course of the planets magnetic field adjust and becomes encased in the recently constructed rock (Trefil & Hazen, 2010).

5) Based on our assumption, we believe that the Mean multiple would be the best measurement for calculating Hertz Terminal Value.

Discuss each of the elements (or prongs) of what must occur to constitute a “search?” What Constitutional protection offers of

5. At a coil current of 3 A, what is the magnetic field produced at the center of the Helmoltz coils in gauss? About what is the magnitude of the Earth’s field in gauss?

If they do not, but are within the acceptable margin of error of ±20√4=±40’’, each angle is corrected to create a sum of 360˚. For this project, the angles added to 360˚ 00’ 10’’. After each angle is corrected, angle 412 is 78˚31’03’’, angle 123 is 99˚01’23’’, angle 234 is 92˚32’21’’, and angle 341 is 89˚53’13’’. After using the Total Station, the Auto level is used to measure the elevations of each point. The known elevation outside of Powell is 380’. The Auto level is placed between each point to measure the backsight and foresight. Once all the points are measured, all the backsights and foresights can be measured with the difference taken to find the error. With this project, the error was -0.128’. Next, the pacing between each point must be taken to find the correction for each elevation with the equation, (distance from known elevation/total level network distance) X total error. The total pacing for the project is 235 steps with a pace of 2.31 feet per step. After the corrections, point 4 is 379.384’, point 3 is 378.182’, point 2 is 379.093’, and point 1 is 379.645’. A transit is used to find the true north from the magnetic

Loosen the retaining screw and adjust the horizontal arm to the dimple that produce the 2nd largest radius between the spinning mass and the rotating shift. Allow the spinning mass to hang straight down, without being connected to the spring. Position the pointer directly below the tip of spinning mass and secure the pointer to the base. Use the scale located on the base to determine the radius, r, of the pointer from the rotating shaft. Record this value onto Data Sheet A. The experimental uncertainty in r is estimated to be the width of the spinning mass tip – approximately 0.2 cm.

5. Find the maximum separation distance from the primary coil along both the vertical and horizontal axes for each of the various secondary coils. Record results.

2. What does the Ammeter (on the left) measure? How is this shown in the simulation?

6) Change the location of the positive charge to at least six widely different distances from the equipotential sensor. Record the voltage reading and distance at each location.

The Teltron Tel 2533 Critical potentials tube contained neon gas kept at fixed, low pressure. Within this tube were a collector ring and a diode electron gun. The filament was kept at a fixed current of 1.2A. Any current higher than this would have done serious damage to the filament. The diode electron gun was used to emit a beam of electrons from its cathode. This beam passed from the cathode through the neon gas present in the tube to the anode. The collector ring within the critical potentials tube was connected to a fixed power supply of 1.25V and a Levell TM8 pA-meter to record the collector current. The fixed power supply of 1.25V was so that the collector ring was made positive relative to the anode. A variable accelerating

where smax is the maximum displacement or displacement amplitude, k is the angular wave number, and w is the angular frequency of the piston.

After obtaining the engineering requirements for the wire, six samples were sent to the lab to be tested.

Case II: The beam was turned around in such way that the shortest side of the cross section is on the support. The steps described in Case I was repeated and data was recorded.
