Answer:

Explanation:
Given that,
Emf, V = 22 mV
Number of turns in the coil us 519
Rate of change of current is 10 A/s.
We need to find the magnetic flux through each turn of the coil at an instant when the current is 3.70 A.
Let's find the inductance first. So,

We have,
,
is magnetic flux

So, the magnetic flux is
.
The total amount of energy remains constant in an isolated system. It implies that energy can neither be created nor destroyed, but can be change from one form to another.
The kinetic energy is

and the height of the building doesn't matter at all.

joules
For those seeking for the answer, its a source of electrical energy.
