What happens to an ionic compound when it is dissolved in water? a liquid crystals are formed. b the ions separate and conduct electricity. c the ions combine and conduct electricity. d the electrons are combined with the water molecules.

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.
