INTRODUCTION

Cancelling Earth’s magnetic field will help with the advancements of scientific innovation. It will make sensitive experiments more realistic and possible. For example, if a scientist were to be conducting an experiment using lasers to produce change particles, the force of the Earth’s magnetic field may be strong enough to cause the particles to change directions and miss the detector. Therefore, the purpose of this experiment was to cancel Earth’s magnetic field. To cancel Earth’s magnetic field, a coil consisting of 38 loops and is 1 meter in diameter was built. The coil itself was made from copper wire that is 2 mm thick. This coil was charged with a current of 1.214 amps and had a voltage of .768 volts. The resistant of the coil is .64 ohms. The results of detecting the Earth’s Magnetic field opposed the initial thought the Earth’s magnetic field was perpendicular to the Earth’s surface. Once the coil was charged with the correct current and voltage an angle of correction had to be determined via a 3-D magnetic probe placed in the center of the coil. A 3-D magnetic probe works just like a compass. It points the cardinal directions according to Earth’s magnetic field. The cancelation of the field was indicated by the probe not indicating a magnetic field presence inside the coil while registering a field outside the coil. Thus, it is concluded that no magnetic field exists within the coil. Therefore, Earth’s magnetic field has been successfully cancelled. The scope of this project is to outline the construction of the device and discuss design enhancement while effectively cancelling Earth’s magnetic field. This will possibly bring forth new and improved scientific laboratories. These new laboratories may be customized for future experiments that can gradually influence and expand scientific ideas.

DATA & ANALYSISCancelling the Earth’s magnetic field can help innovate scientific research. The Earth’s magnetic field can be a limiting factor when conducting certain experiments. For example, if a researcher was doing an experiment involving the shooting of a particle electron beam, the Earth’s magnetic field would have to be cancelled. If the beam may be aimed at a certain detector, the Earth’s magnetic field may be strong enough to change the direction of the beam depending on the area of the lab. Therefore, this experiment may help shape a way to create laboratories with a magnetic control, thus making experiments like the one mentioned above much easier, more realistic, and possible.

MATERIALS

PROCEDURE1. Gather all materials2. Lay out 119 inches of copper wire from a 400 feet spool3. Make a circular loop shape by putting both ends of the wire together (do not cut wire off of 400 feet

spool)4. Take both ends of the wire and tie then together using the aluminum string tie5. Continuing spinning the rest of the 400 feet of copper wire fallowing the same direction. (Note: use the

steel tie to tie down each new loop to previous loop(s). Tie down each loop where necessary)6. Make sure the copper coil is firmly tied together. Find the two ends of the coil and use the pocket knife

to remove the enamel coating off of the two ends only7. Cut 14 feet aluminum T- slotted framing into 7 pieces (each 2 feet long)8. Construct a square using 4 pieces of the aluminum T-slotted framing9. Use the clamps and fasteners hold a constant and firm square shape10.Inscribe the square into the coil11.Use the steel string tie to tie each corner of the square onto the coil12.Connect two aluminum T-slotted framing pieces to the top side of the square using the bracket

fasteners (these are legs)13.Cut a two and a half inch length of aluminum T-slotted framing from the last piece of framing material14.Connect the two and half inch piece to the bottom side of the square using the fasteners (the coil should

now be standing at an angle)15.Take one end of the coil (that you have previously stripped of enamel coating) and connect it to the

middle ring of the potentiometer by using the solder and solder iron16.Take the second end of the coil (that you previously stripped from enamel coating) and place it to one

end of the battery pack. Solder the ends together using the solder iron and the solder itself17. Take 1 foot of copper wire, cut it using the pliers to needed length and strip each end from enamel

coating using the pocket knife18.Connect one end of the copper wire that you just stripped to the second end of the batter pack using the

solder and solder iron19.Connect the second end of the copper wire onto the far right or far left ring of the potentiometer using

the solder and solder iron20.Place the D size battery into the battery pack and use the potentiometer to control the current and test

your coil

RESULTSFrom the data and analysis, we can conclude the fallowing factors of the coil: the current is 1.214 amps, the resistance is .64 ohms, and the voltage is .768 volts. When a magnetic probe is placed in the center of the coil while applying these factors, the magnetic probe will not point any directions and can be manually adjusted to the direction one desires. Therefore, when these factors are applied to the coil, the magnetic field within the coil is canceled.
