Hello students.
00:02
Now in this question they have given the circular coil which has 100 turns and which has the radius of about 10 cm.
00:15
It lies in a magnetic field and which has the magnitude of above magnetic field is 0 .06 50 nesla and which is perpendicular to the coil they have given.
00:28
And they are asking us to calculate here two questions.
00:31
Yet first sub question is that we have to find the magnetic flux through the coil and second one.
00:35
Instead we have to find the magnetic field through the coil which is increases steadily to the 0 .01 tesla over time interval of time t is equal to 0 .05 seconds.
00:47
Now in the first sub question we have to calculate the magnetic flux through the coil.
00:53
So to find the magnetic flux through the coil we can use the formula.
00:57
Flux 5 is equal to b into a into cost theta.
01:04
Here 5 is the magnetic.
01:07
Flux b is the magnetic field and a is the area of the coil and teta is the angle between the magnetic field and normal to the coil so in this case magnetic field is perpendicular to the coil hence teta is equal to zero also area of the coil a is equal to pi into r square then pi into r square is 0 .1 meter square which is equal to 0 .314 meter square and area is equal to 0 .314 meter square.
01:40
Substitute in the given values in the 5 equation we have 5 is equal to 0 .0650 tesla into 0 .314, sorry, 0 .0314 .14 meter square into cost 0 .00 into 100 tons.
02:05
So by substituting these we will get answer as 5 is equal to 20 .4 jowl per tesla.
02:21
Therefore magnetic flux through the coil is 20 .4 jowl per tesla.
02:26
Next coming to the second sub question we have to find the magnitude of the induced emf...
