Explanation:
Given that,
Induced emf
Rate of current = 0.250 A/s
Number of turns =30
(a). We need to calculate the mutual inductance of the pair of coils
Using formula of the mutual inductance
The mutual inductance of the pair of coils is 6.6 mHz.
(b). We need to calculate the flux through each turn
Using formula of flux
Put the value into the formula
The flux through each turn is
(c). We need to calculate the magnitude of the induced emf in the first coil
Using formula of induced emf
The magnitude of the induced emf in the first coil is
Hence, This is the required solution.
To solve this problem it is necessary to apply the concepts related to electromotive force or induced voltage.
By definition we know that the induced emf in the loop is equal to the negative of the change in the magnetic field, that is,
Where A is the area of the loop, B the magnetic field and t the time.
Replacing with our values we have that
Therefore the thermal energy produced is given by
The thermal energy produced in the loop is
1radian<span> = 180/ degrees

<span>The tides are produce by the difference in the moon’s gravitational force across
the earth, creating a bulge on the surface of the ocean and a bulge on the
opposite side of the earth. With this, an </span>oval is seen around
Earth that points toward and away from the moon to show the tidal bulges. This
image shows that the ocean
bulges on both the side of the earth facing the moon and the side opposite the
moon.
