The Magnetic Field (long, straight wire) is found using the following formula: `B=k/c^2*(2*I)/r`, where:
- `B` = Magnetic Field created by a long, straight wire carrying current `I`
- `k` = Coulomb's Constant ()
- `c` = relativity constant (speed of light - 2.99792458E8 m/s)
- `I` = current
- `r` = distance from the center wire
