Complete the table below by measuring the compass needle orientation for different locations of the bar magnet along the ruler. The distance d is measured from the center of the compass (i.e. 10 cm mark) to the center of the bar magnet. Calculate the strength of bar magnet's field at each location to 3 significant figures, assuming the strength of the Earth's field is 0.5 Gauss (i.e. Bearth-0.5 Gauss) Orientation ofMagnetic Field of Compass Needle Distance Bar Magnet bar (Gauss) (cm) 30 35 40 45 50 60 70 80 50 40 30 20 10 10 2.38 1.68 1.15 0.728 0.353 0.353 0.281 0.140 4 O Type here to search 7:48 PM 3/18/2019 1

Bar Magnet

In physics, magnetism is a phenomenon exhibited by a magnetic substance that exerts either attractive or repulsive force. A bar magnet is either a rectangular or round and hollow fit comprised of ferromagnetic materials and has a fanciful attractive field surrounded by it.
