MODIFICATION: Magnetic Field Strength and Temperature I'm not sure if I should have made the coil shorter in length by winding the wire over itself - perhaps it would be better but I wanted to be able to count the turns easily. This makes an ideal EEI as you can modify your design in an attempt to reduce the error. The actual value from GeoScience Australia for the date and location was 55.154 μT, hence my error was 8% (which is quite large). For my B H of 32.2 μT divided by cos 57° I get a B E of 59.7 μT. My measurement of "dip" was 57° South-down (the accepted value for Brisbane is 57.4°).
The declination angle can be measured by a "dip needle" which should be available in most Science Departments. Lastly, once you have B H you can calculate B E (the overall magnetic field strength of the Earth at that location) by dividing by the cos of the local declination angle. The slope is shown by the "y= 32.178x" which means the horizontal component (B H) of the Earth's magnetic field strength was 32.178 μT (microtesla). Jon Williams of Bowling Green State University, Ohio, USA. They were orientated so their axis was East-West (at 90° to the compass). I used clear plastic of diameter 109 mm (R = 0.045 m), and wound 25 turns of wire on each one (N = 25). Plastic water pipe is fine for the coils.
I placed the compass on a little stand so that it was in the centre of the coils. The setup I made was two Helmholz coils with a gap between them for the compass.

The constant μ o is the permeability of free space (4πx10 -7 Tm/A). You can use the Biot-Savart Law to determine magnetic field strength due to the coil: B C = 8 μ oNI/(R x 5√5) where N = number of turns on each coil (not the total), I is the current, R is the radius of the coil. If you can get the needle to move to 45° it means that the coil's field is the same magnitude as the Earth's field - but just acting at right angles. If you place a compass on a bench and let it point north, you can make it move towards the east or west by placing a magnetic field at right angles to the compass direction. In this EEI, you could measure the local magnetic field by comparing it to a know value created by a coil of known size, current, and turns. As electromagnetic theory was developed through the 1800s it was found that magnetic field strengths could be given absolute values by the use of a coil carrying an electrical current. Up until the 1830s it was difficult to measure the magnetic field of the Earth quantitatively because there were no real standard to compare it against.
