What will happen if there is a change in a magnetic field? A. The magnetic field will increase. B. The magnetic field will decrease. C. An electric field will be produced. D. The magnetic field will collapse.

 i think the best answer would be B.

D. the magnetic field would collapse

Explanation:

The earth magnetic field is protecting the atmosphere from the solar wind any sudden changes will cause navigational disaster.

that would be because of both gravity and friction. so     c

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
