Question

1) Write an activity to show that the Strength of the bar
Magnet is Maximum near the Poles ?​

Answer 1

Explanation:

The magnetic field lines near the center are parallel to the length of the bar. Moreover, the density of the field lines is maximized at the "poles" of the bar magnet and minimized at the center which means that the magnitude of the magnetic field is smallest at the center. That is, in the middle the magnetic lines are far away from one another and at the poles are close to each other that is why at the center the magnetic force is less than the poles.

Answer 2

Answer:

place a bar magnet on a table and put some iron fillings on it after some time we can see that the iron fillings are attached mostly at the two ends and very less at the body. Through this activity we can illustrate that magnet is maximum near the poles.
