Magnetic Force on a Wire (F = BIL)
F = B·I·L
What it means
The force on a current-carrying wire in a magnetic field, depending on field strength, current, and wire length.
Variables
| Symbol | Quantity | SI unit |
|---|---|---|
F | force | N |
B | magnetic field | T |
I | current | A |
L | length | m |
Worked example
Given B = 0.5 T, I = 2 A, L = 3 m, solve for F:
F = 3 N
