**1. The problem statement, all variables and given/known data**

A long wire carrying 6.50A of current makes two bends. The bent part of the wire passes through a uniform 0.280T magnetic field directed as shown in the figure and confined to a limited region of space.

Part A: Find the magnitude of the force that the magnetic field exerts on the wire.

Part B: Find the direction of the force that the magnetic field exerts on the wire.

here is the link for the figure. http://ift.tt/1gYnzS0

**2. Relevant equations**

F=IlB

**3. The attempt at a solution**

I= 6.50A, B= 0.280T, and l=0.8m(I did the Pythagorean theorem to find the lenght)

F=(6.50A)(0.8m)(0.280T)

F= 1.456N.

I found the force, but I got the answer wrong. Can someone explain where did I go wrong? I’m confuse with this problem.
