its plane is perpendicular to a magnetic field of 0.68 $\mathrm{T}$
pointing up. During the course of 0.16 $\mathrm{s}$ , the field is changed
to one of 0.25 $\mathrm{T}$ pointing down. What is the average induced
emf in the coil?

Hi and given problem Dia meter. The oil is and 0.2 centimeters. So x radius really hard off the diameter. These 10 points to be invited by you, centimeter for you can see 5.1 intended ar minus two meet up. No, Initially a magnetically linked to the oil perpendicular early is Do you know why? 63 Yes. Lock me out of the quite and a prep Time D is 4 to 0.15 seconds. This magnetic group becomes seed. Applying you fi Tesla in downward direction means extraction is also changed. So we put a negative sign village and according to Faraday's laws off electromagnetic induction The emitting news to the koi We begin by dying Read off change or magnetic flux The negative all timed it off. Change of magnetic flux. So here it becomes I do. Which is me too, into a 51 which is even into it divided by nine. Or you can see negative or the to minus Leven divided by time area. An area we know this is by into our sweat. So putting these values we get for me too This is minus 0.25 and for even this is 0.63 Yes, look. Divided by 0.1 fight and for area is in spite by one poor are square means 5.1 Standish ar minus two the whole square. And when we calculated this value comes out to be whole 0.79 into temptation ar minus two board or you can see 4.8 into 10. Dish ar minus two full. This is the inner induced in the Given coy Thank you.

This is Chapter twenty one. Problem number six. We have a wire coil of diameter, ten point eight seven years and it's a medicine, an external be field. It is perpendicular to it, and the initial magnetic field is pointing up in the magnitude or point for eight Testa. So this is and then within point one six seconds. The field. The field has changed to a downward field, so that's from the negative here to refer to that magnitude a point two five Teslas. Now we're asked to calculate the average induced AM up in this case, the wire core. So as you know, the induced ANA is going home, changing the flux rate of change of clicks. In this case, the magnetic flux is doing that. It feels times the cross sectional area area is constant. In this case, however, Thea bombing that fuel this changing with respect to time and again. Let's write the area. It's pi tea over to swear right Delta Bi though it is the final minus the initial right, so pie would be well, let's add diminutive here I would be more three point one four d would be on ten point eight centimetres. Sold ten point eight times ten to borrow. Two meters, right. Divided by half. Bye bye, too. Help! I'm squared. And then we have the final magnetic field to be negative. Point two five Tesler minus initial is point for eight. Tesla here. Right. And this is divided by the time miserable. Every have point mon. Six seconds. This's so they calculate when we find out that the induced average Emma is actually positive for it. One negative here, another negative from the changing magnetic field. So it's going to turn out to be four point eight times tender from me, too.

Hi. In the given problem, the diameter off the loop off a wire has been given as well. Tzeitel. Centimeter. So radios off this loop will become Do you buy two or we can see 12.0 by two centimeter or it's expired. Zero in tow. 10 Bishop R minus two meter. No, the flux. The magnetic flux linked through the koi is given us. If we consider this as the area element, this is DS and this is the magnetic career. Be and this is the angle between them. Then we know the magnetic flux linked to the oil is giving us the dot product off magnetic field with the idea. So it becomes be D s calls Teeter. So here, in this formula angle is between the normal runner up enough oil and the magnetic field. So in the given problem, it is given that the loop is perpendicular to the magnetic field. So then loop is simply perpendicular to the magnetic field that is angle between area vector and magnetic field. We become zero degree. So in first case of flux, we become be into a into cause zero degree, or we can say it becomes being to it. Finally, it is said that the court is rotated. Such a there explain becomes parallel to the magnetic rear. And when the plane off oil becomes parallel to the magnetic field, then there will be no flux linked to the oil because the angle in that case will be trying to really Certainly it could become cost 90 degree, which is zero. So the final flux we become zero. So Aspar Lenses Law the E M F IND used in the given time and the time given here is 0.20 2nd So the MF induced become the time rate off change off magnetic locks so that quite and it will be given by minors, be to sorry, this would be only this would be given by B A course 90 degree minus B a cause zero degree. Already we know these values divided by dying, so it becomes minus zero minus 1.5 for magnetic field, which has given us 1.5 s la into your area by our square by 3.14 for our square. This is six into 10 days to the par minus school, the whole square we're trying. This is zero point those little. So when we calculate it Finally the MF in news comes out to be it going five in tow, 10 days apart, minus two Ward, this is the aim of induced through the sky when explain is turned through 90 degree. Thank you.

Hi. The given problem We are having a coil in which the number of grounds is 50 Iria off. This coil has been given us then sending needed to square. Or we can say this is Ben in 10 dish a par minus four meter square which can further billiton as Ben Detective bottom minus treat. I need you to swear the scar is flipped in. A magnetic field which is having a magnitude off initial magnitude can be taken as blesses. You don't want 75 Destler and then the oil slipped at an angle off. One of duty so effectively magnetic feared, can be digging as minus 0.75 Yes, look as a directional though coy is reversed. True 20 degree and the time in which it is flipped is given a zero point toe zero second. So ask for Faraday's laws off electromagnetic induction. The IMF in news you've been given ass minus and time. So time right off, change off magnetic locks passing through this coil and the expression for magnet flux is product off magnetic field with the area. This becomes B two a minus. Stephen, it divided by John. So putting these a loser. This is minus 50 or B two. This is minus 0.75 into area. Dandridge's Bar, Minor Street for Beaven. This is plus your 0.75 into again area standards for minor street. Four time. This is 0.20 2nd. So yeah, it comes out to be positive. 50 minus minus positive into 10 days apart minus three into 3.750 point 75 will become 1.5 divided by 0.2 wallet. So average really off The CMF induced Finally comes out to be 0.375 board. So this is the answer for the human problem. Thank you.
