The intensity of the magnetic force exerted on the wire due to the presence of the magnetic field is given by
where
I is the current in the wire
L is the length of the wire
B is the magnetic field intensity
is the angle between the direction of the wire and the magnetic field
In our problem, L=65 cm=0.65 m, I=0.35 A and B=1.24 T. The force on the wire is F=0.26 N, therefore we can rearrange the equation to find the sine of the angle:
and so, the angle is
