Can you make a magnet be more magnetic (attracting with greater intensity) by using a variable voltage source and increasing the amplitude?
Like if I attached an iron blob to something, and had a magnet being powered by an electric circuit nearby. By increasing the intensity of the circuit, would this cause the magnet to pull on the iron blob even greater?
