Explain any two effects of refraction of light experienced by you​

1) during monsoon light passing through the water surface refracts causing the formation of rainbow.

2) a swimming pool looks more shallower than it actually is because the light coming from the bottom of the pool bends when it comes out at the surface due to refraction of light.

Explanation:

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
