Force on current carrying wire

  • #1

A straight wire of length 90 cm carries a current of 60 A and makes an angle of 45 degrees with a uniform magnetic field. If the force on the wire is 2.0 N what is the magnitude of B.

my attempt:
F=BIL
2=B(6)(.90)
B=.37
What am i doing wrong?

F=BIL is assuming the conductor is at 90 degrees to the magnetic field.

if it is at an angle [itex]\theta[/itex], then the formula becomes [itex]F=BILsin\theta[/itex]
