Design an experiment to determine the strength of the magnetic
field of Earth using the available equipment.
Available equipment: A large coil of wire (with stand
in the center), compass, ammeter, 10Ω and 50Ω resistors, power
supply, ruler.
A) Perform the experiment and record your measurement and
calculations in an appropriate format. Be explicit about what model
you're using to calculate the magnetic field. Vector diagrams may
assists you. Include important measurements. Determine the
magnitude of the Earth's magnetic field....
