adding a(n) to an electric circuit would increase the magnetic field around a wire;
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.
the answer is to check all of them! they all apply well at least i think so!
Large empty spaces in the universe are called voids. The most abundant element in the universe is hydrogen. The second most abundant element is helium.
