Based on the tug of war pictured below, what is the net force?

–190 N
10 N
–10 N
190 N

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.

grav forces affect all objects magnetic forces affect magnetic objects and electric currents
