A particular Alnico (aluminum, cobalt, nickel, and iron) bar magnet (magnet A) has a mass of 10 g. It produces a magnetic field of magnitude 6e-05 T at a location 0.18 m from the center of the magnet, on the axis of the magnet.

(a) Approximately what is the magnitude of the magnetic field of magnet A a distance of 0.36 m from the center of the magnet, along the same axis?

|A| = T

(b) If you removed the original magnet, and replaced it with a magnet made of the same material, but with a mass of 30 g (magnet B), approximately what would be the magnetic field at a location 0.18 m from the center of the magnet, on the axis of the magnet?

|B| = T
