For each slide calculate the thickness of the nickel coating, 푥, using beer’s law. assume that the optical attenuation coefficient for nickel is equal to 훼=1 ×108 m−1. give your answers in nanometers, nm = 10−9 m.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

increase masses, decrease separation
