38. The strength of a magnetic field is called magnetic iduction. An equation for magnetic induction is B= F/IL sin theta, where F is a force on a current I which is moving through a wire of length L at an angle theta to the magnetic field. A wire within a magnetic field is 1 meter long and carries a current of 5.04 N/Am. What is the angle of the wire to the magnetic field?[/COLOR]

1. You need to employ brackets to make your equations unambiguous.
I guess you mean:

$B=F/(I.L.\sin(\theta))$

2. You give insufficient data to allow the determination of $\theta$.
Even if we assume that when you say the current is $5.04 N/Am$
(the units seem to be Newtons/Amp !?) you actually mean $F/I$ is
$5.04 N/Am$.
