Charge of 4.5 x 10^-5 C is placed an electric field with the strength of 2.0 x 10^4 N/C. If the charge is 0.030M from the source of the electric field, what is the electric potential energy of the charge?

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.
