Physics
In an experiment, a student placed a sheet of paper on a bar magnet, and iron filings were sprinkled on the
sheet of paper. Thereafter, the paper was gently tapped. The diagram below shows the final result of the experiment

Ответ:
a. Aim of the experiment: To identify the magnetic fields around the bar magnet.
b. After tapping the paper, the iron filings align themselves according to the lines of the magnetic force of bar magnet. The magnetic field is more concentrated at the ends of poles as most of the iron fillings are attracted at the poles and the pattern form by iron filling shows the magnetic field of the bar magnet.
c. If iron filings will be replaced with grit, there will be no magnetic movement around bar magnet as grit is not a metal and do not have any magnetic properties.
Ответ:
Kinematics is a subfield of physics, developed in classical mechanics, that describes the motion of points, bodies, and systems of bodies without considering the forces that cause them to move.
