Along straight wire of circular cross section with radius r_0 carries current i and is immersed in a large volume of water. the wire is nonmagnetic. calculate the magnetization m(x) in the water. (the susceptibility is -9.0 times 10^-6) what is the bound current density j_b (x) for r > r_0? calculate the total current (free plus bound).

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
