While doing a lab, a student found the density of a piece of pure aluminum to be 2.85 g/cm. the accepted value for the density of aluminum is 2.70 g/cm. what was the students percent error?

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.
