6. A wire is formed so as to make a circular loop connecting two long, straight sections as shown in Figure 6. If the radius of the loop is R = 20 cm and the wire carries a current I = 2.4 A, what are the magnitude and direction of the magnetic field at the center of the loop? If needed, you can use the magnetic field due to a straight wire, and and the magnetic field at the center of a loop derived from Ampere's law. (Hint: The two long sections form one long straight current- carrying wire.)

A particle’s path is bent when it passes through a region of non-zero magnetic field although its speed remains unchanged. This is very useful for “beam steering’’ in particle accelerators.

By how much angle will the path of the proton be bent? (Hint: the particle comes out tangent to a circle.
