Length of the wire that is inside the magnetic field

  • #1

Homework Statement



The magnetic force acting on a wire that is
perpendicular to a 5.3 T uniform magnetic
field is 6.5 N.
If the current in the wire is 5.0 A, what
is the length of the wire that is inside the
magnetic field?
Answer in units of m.


Homework Equations



F = B . I . L


The Attempt at a Solution



L = F / B . I = 6.5 / 5.3 . 5 = 0.25 m

this is what I did, but the hw system says its wrong.
