Answer:

We have that θ is the angle that makes the normal of the loop and the direction of the magnetic field.

This means that if θ = 0°, the plane in which the loop of wire lies is totally perpendicular to the magnetic field. (or the face of the loop points in the same direction than the field)

Now, the magnetic flux can be calculated as:

\int\limits^} \,B.dA

Where dA is the differential of area, and we have a dot product, then we have:

B.dA = B*Acos(θ)ds

ds is a differential of surface.

Now, the flux will be maximum when cos(θ) is also a maximum.

And the maximum of the cosine is:

Cos(0°) = 1.

decreasing until cos(90°) = 0

Now, the options given are:

30°, 45°, 60° and 90°.

Then in this range, the maximum flux will occur at the angle closer to 0°, then the correct option is θ = 30°

How does the gravity which pulls the moon and earth toward each other also affect the ocean?
slamgirl [31]
Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made.
