A square loop whose sides are long is made of copper wire of radius , given the resistivity of copper is . if the magnetic field perpendicular to the loop changes at a constant rate of I = 14.029 mA.
The basic characteristic of a substance that measures how effectively it resists an electric current is called electrical resistance. A material with low resistance is a material that easily conducts electric current. A Greek letter is often used to indicate resistivity. Electrical resistance is a basic property of a material that measures how strongly it resists an electric current. The SI unit for electrical resistance is the ohmmeter.
We use magnetic field as a tool to describe how the magnetic field is distributed in the space around and inside something of a magnetic nature. A material with low resistance is a material that easily conducts electric current. A Greek letter is often used to indicate resistivity. An ohmmeter is a unit of electrical resistance in the SI system.

The complete question is :
A square loop whose sides are 6.0-cm long is made with copper wire of radius 1.0 mm. If a magnetic field perpendicular to the loop is changing at a rate of 5.0 mT/s, what is the current in the loop?

Answer:
Explanation:
Suppose v is the initial velocity and
is the angle of inclination
distance traveled in vertical direction in t=1 s
When gravity is present
![y=vt+\frac{1}{2}at^2](https://tex.z-dn.net/?f=y%3Dvt%2B%5Cfrac%7B1%7D%7B2%7Dat%5E2)
where ![y=vertical\ distance](https://tex.z-dn.net/?f=y%3Dvertical%5C%20distance)
![a=acceleration](https://tex.z-dn.net/?f=a%3Dacceleration)
![t=time](https://tex.z-dn.net/?f=t%3Dtime)
![v=initial\ velocity](https://tex.z-dn.net/?f=v%3Dinitial%5C%20velocity)
here initial velocity is v\sin \theta [/tex] so
![y=v\sin \theta \times 1-\frac{1}{2}gt^2](https://tex.z-dn.net/?f=y%3Dv%5Csin%20%5Ctheta%20%5Ctimes%201-%5Cfrac%7B1%7D%7B2%7Dgt%5E2)
![y=v\sin \theta -0.5g](https://tex.z-dn.net/?f=y%3Dv%5Csin%20%5Ctheta%20-0.5g)
In absence of gravity
![y_2=v\sin \theta \times t](https://tex.z-dn.net/?f=y_2%3Dv%5Csin%20%5Ctheta%20%5Ctimes%20t)
![y_2=v\sin \theta \times 1](https://tex.z-dn.net/?f=y_2%3Dv%5Csin%20%5Ctheta%20%5Ctimes%201)
![\Delta y=y_2-y=v\sin \theta -v\sin \theta +0.5 g=4.9\ m](https://tex.z-dn.net/?f=%5CDelta%20y%3Dy_2-y%3Dv%5Csin%20%5Ctheta%20-v%5Csin%20%5Ctheta%20%2B0.5%20g%3D4.9%5C%20m)
