= Thermal coefficient of marble =
= Initial length = 170 m
= Change in temperature = (-10-35)°C
Change in length is given by
The height on the given day will be
The magnetic field strength is 17 Weber.
<h3>How can we find the value of magnetic field?</h3>We know, The magnetic field equation is given by:
Where, we know,
=
= It is the magnetic constant or the permeability of free space.
n = The turn density which is equivalent to number of turns per unit length = 3300 turns per meter = 3300
I= the amount of current applied to it = 4. 1 kA = 4 × A.
We have to find the magnetic field strength = B
Substituting the known values into the equation gives the strength of the magnetic field, which is:
[We know,
]
So, from the above calculation we can see that, The magnetic field strength is 17 Weber.
