A circular loop of wire with area A lies in the xy-plane. As viewed along the z-axis looking in the âˆ’z-direction toward the origin, a current I is circulating clockwise around the loop. The torque produced by an external magnetic field B is given by Ï„ = D (5i^ - 2j^), where D is a positive constant, and for this orientation of the loop the magnetic potential energy U = âˆ’Î¼ * B is negative. The magnitude of the magnetic field is B0 = 13D/IA.
A) Determine the vector magnetic moment of the current loop.
B) Determine the component Bx of B.
C) Determine the component By of B.

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
