Is the force of 20 Newton and displacement to M are acting in opposite direction then find the work done

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

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.
