Explanation / Answer

1)qvB = mv^2/r
=>B = mv^2/qvr = mv/qr
=>B = [{6.6 x 10^-27 x 1.7 x 10^6}/{2 x 1.6 x 10^-19 x 0.13}]
=>B = 0.27 Tesla

2)

Magnetic force per unit length = B*I*sin(theta)
Part A:

When perpendicular, force per unit length = B*I*sin(90) = B*I = 0.6T*9.20A = 5.52 N/m

Part B:

At 45 deg, force per unit length = B*I*sin(45) = 0.6T*9.20A*0.707 = 3.9 N/m
