A uniform magnetic field passes through two areas, A1 and A2. The angles between the magnetic field and the normal directions of areas A1 and A2 are 30° and 60°, respectively. If the magnetic flux through the two areas is the same, what is the ratio A1/A2? A. 0.577
B. 0.816
C. 1.00
D. 1.23

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

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.

not copied too! hope this !
