Point a is on the +y-axis at y = +0.250 m and point b is on the +x-axis at x = + 0.250 m. A wire in the shape of a circular arc of radius 0.200 m and centered on the origin goes from a to b and carries current I = 5.50 A in the direction from a to b.

If the wire is in a uniform magnetic field B = 0.800 T in the +z-dirction, what is the magnitude of the net force that the magnetic field exerts on the wire segment?

What is the direction of the net force that the magnetic field exerts on the wire segment?

What is the magnitude of the net force on the wire if the field is B = 0.800 T in the +x-direction?

What is the direction of the net force on the wire if the field is B = 0.800 T in the +x-direction?
