Explanation:
Given:
For the first solenoid
Number of turns, n₁ = 1200 turns/m
Current, I₁ = 2.5 A
Paramagnetic material temperature, T₁ = 320 K
Now for the second solenoid
Number of turns, n₂ = 1000 turns/m
Current, I₂ = 0.85 A
Paramagnetic material temperature = T₂
The magnetic flux (B) is given as
where,
c = curie's constant
μ₀ = arithmetic constant
also it is given that the magnetization in both the cases are same
therefore the magnetic flux will also be equal
thus,

Waves can and do meet boundaries in their medium. When a wave meets a boundary, it can be reflected or transmitted. ... Refraction occurs when a wave crosses a boundary from one medium to another. A wave entering a medium at an angle will change direction.

Answer:
The answer is "Option d".
Explanation:
In the given scenario, when a surface is drawn in a magnetic field, the number of magnetic field lines that enter a surface must be equal to the number left because we know that magnetic field lines are always a closed curve hence the number of magnetic field lines that join the surface should match the total left.
