<span>From Ohm's law. V = IR. Where R = 2 Ohms. To calculate the induced current I; We need to calculate the electromotive force or voltage, V. From Faraday's law induced EMF = (The rate of change of magnetic flux density x Area)/ (changein time). Or EMF = BA/t. Where B = Bf - Bi. And BA = Bf* A - Bi* A.
Bf = 2.00 and Bi = 0.500 and t = 0.93s and the area, A = 7.1 cm^2 is 0.000071 m^2. 2
So Emf = 2.00 (0.000071) - 0.500(0.000071) /(0.93) = 1.0654 * 10^(-4)/ 0.93 = 1.1415 * 10^(-4).
Substituting into ohms law, we have,
I = (1.1415 * 10^(-4)) / 2 = 0.57075 * 10^(-4)</span>
You apparently haven't noticed yet . . .
The moon rises in the East, moves across the sky, and sets
in the West, just like the sun and everything else in the sky.
It takes the moon about 12 hours and 25 minutes to go from
rising to setting, and then it rises again about 24 hours and
49 minutes later. So each day, the moon rises about 49 minutes
later than it rose on the previous day.
In order to describe the direction and height of the moon in the sky,
you need to tell the date and the time, and also the latitude on Earth
from which you observed it. And wherever the moon was in the sky
at that time, it was in a noticeably different place 30 minutes later.
Just like the sun.

Answer:
The magnetic field is 14.08 T.
Explanation:
Given that,
Speed of electron 
Distance 
Suppose we need to find the magnetic field at the location of the proton
We need to calculate the magnetic field
Using formula of magnetic field
....(I)
Using formula of current
Using formula of time
Put the value of current and time in equation (I)
Put the value into the formula
Hence, The magnetic field is 14.08 T.
