Answer:
The magnetic flux links to its turns = Wb.
Explanation:
Given :
Radius of circular coil = m
Number of turns = 25
Magnetic field = T
Magnetic flux (Φ) is a measure of the magnetic field lines passes through a given area. The unit of magnetic flux is weber (Wb).
We know that,
⇒ Φ =
Where ext. magnetic field,
area of loop or coil.
But here given in question, we have turns of wire so our above eq. modified as follows.
⇒ Φ =
Where no. of turns.
∴ Φ =
Φ =
Thus, the magnetic flux links to its turns =
