Object a has less thermal energy than object b, but heat flows from object a to object b. what conditions would make it possible?

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.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
