Explanation / Answer

1. As we know that the light emitted by the sun is polarized by magnetic fields.

A polarimeter can easily see the different direction of the light from sun, and then can easily detect inference of the magnetic fields.

2.

Neutrinos are one of the Basic Particlesofthe universe . They are similar to e-, but they do not have charge, thats why they are not affected by the electromagnetic forces. They are affected by a "weak" sub-atomic force of shorter range than electromagnetism, because of this are able to pass through large distances in matter.

3.

AsNeutrinos are a byproduct of nuclear fusion that is taking place on Sun.They are important because the neutrino count from sun can easily give an indication to the amount of nuclear fusion that is taking place inside the Sun.

4.

Unable to Detect Nutrino particle from a fusion is Solar Nutrino Problem
