| Quantity: |
magnetic tension
|
| Concept definition: |
The integral from ra to rb of H ·dr, where H is magnetic field strength [IEC 80000-6:2008, item 6-25] and r is position vector [ISO 80000-3:2006, item 3-1.11] along a given curve C from point a to point b. For an irrotational magnetic field strength, this quantity is equal to the magnetic potential difference. |

electric current
|
| Concept definition: |
That constant electric current which, if maintained in two parallel conductors of infinite length, of negligible circular cross-section, and placed 1 metre apart in vacuum, would produce between these conductors a force equal to 2 x 10-7 newton per metre of length.
