If the magnitude of the drift velocity of free electrons in a copper wire is 7.54 10-4 m/s, what is the electric field in the conductor

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.

the right answer is 0.3 meters per second
