A large stick is pivoted about one end and allowed to swing back and forth with no friction as a physical pendulum. The mass of the stick is 3.0 kg and its center of gravity (found by finding its balance point) is 2.6 m from the pivot. If the period of the swinging stick is 8 seconds, what is the moment of inertia of the stick about an axis through the pivot

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.
