Answer:
please look at the following picture:)
Explanation:
A bar magnet with its south pole on the left is describes the object on the right. A bar magnet's magnetic field is stronger at either pole of the magnet. When compared to the south pole, it is similarly strong at the north pole.
<h3 /><h3>What is bar magnet and its types?</h3>
There are two types of rectangular magnets fashioned like bars: cylindrical bar magnets and rectangular bar magnets.
Both types of bar magnets are capable of producing a powerful magnetic field. A rod magnet is a cylindrical bar magnet that is also known as a rod magnet.
Thus option D is correct.

No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect
<h3>Perpendicular lines</h3>
In order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:
For the slope of lm:

For the slope of ln:

For the slope of mn:

- If any of the two lines is perpendicular, hence the triangle lmn is right-angled.
- To check, we will take the product of the slopes and see if it is equivalent to -1.
Product of slope lm and ln

Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect
