Enter a value for all fields
The Magnetic Field (single, circular loop) is found using the following formula: `B=k/c^2 2piIb^2(b^2+z^2)^(-3/2)`, where:
- `B` = Magnetic Field created by a long, straight wire carrying current `I`
- `k` = Coulomb's Constant
- `pi` = 3.14159265358979323846264338327950288
- `c` = relativity constant (speed of light)
- `I` = current
- `b` = radius of the loop
- 'z' = distance of point from plane of loop
