The magnetic field between the poles of an electromagnet is $2.6 \mathrm{T} .$ A coil of wire is placed in this region so that the field is parallel to the axis of the coil. The coil has electrical resistance $25 \Omega,$ radius $1.8 \mathrm{cm},$ and length $12.0 \mathrm{cm} .$ When the current supply to the electromagnet is shut off, the total charge that flows through the coil is $9.0 \mathrm{mC} .$ How many turns are there in the coil?

Hi. In the given problem magnetic field between the pools, all electro magnet is given as B one is equal to 2.6 Tesla, as this field is parallel to the axis of the coil, which is kept between the poles of the magnet so you can see angle between Madrid equal vector and area. Vector is zero. Theta is equal to zero degree resistance of this coil just given us up is equal to 25 mm and radius of the coil is 1.8 centimetre. Or we can say this is 1.8 into tennis. Part minus two. NATO. No. Then current to electro magnet is shut off. The magnetic field induced in it means be too, will drop to zero. And then it is measured that the church passing through the coil is equal to 9.0 Millie Gulen. So now, using the expression for MF induced as per Faraday's law of electromagnetic induction, excellent means enough induced is given as minus and times of five to minus five won by t the time rate of change of magnetic flux linked through the coil. So this is minus n times of for the final magnetic plugs. This is B two into a into cost hitter, minus for the initial magnetic locks. B one A into cost hitter divided by John. But as the B two is zero, so it comes out to the end into even into pie are square cost heater bye deep. So the current passing through the current induced in the coil will be given by Home Slope as a silent by art means. This will be given us and into given into by our square for cost. We can write it because zero degree, whose value will be one divided by D into our and this current induced can also be given us the time rate off flow of charge mean skewed by t. So canceling this tea, the expression for charge here comes out to be Q is equal to and even by our square by art and into the one by our square bye are so finally the number of times an expression for the number of times will be Q into our divided by be one into five into our square. So finally plugging in all known values here for the charge passing through this coil which is 9.0 into tended bar minus three colon into resistance 25 home divided by magnetic field, which is 2.6 Tesla in 23.14 for the value of pi into radius, The square of radius is 1.8 into 10 days. Par minus two to the whole square. So finally this number of currents here comes out to be it deep fight, which is the answer for the given problem. Thank you.

Well, someone. Well, Brooke was yet one is girl world under now that is going to it. Didn't eyes glowing in grade one and authentic log one direction is shining people well behind what we go melody clubs through the quite do do you do great. One is you know, the community clubs is one by doctor or that dog magnetic field and the area and and go between bar, particularly in the area. So in this case, in quite won, an empty black was grain flows. It produces a Merete feeling direction off, out, off our to ours of out of the cage that is to ask us So direction is all about big. So keep that in this case And today's angle between the men, particularly in the area, which is and just guess our area is held in a certain direction horizontally and there is direction is upward. So the magnetic flux is off days. So they in this direction that is, do ours. The US and again, the lunatic very of the So yeah, about three dimensions Here. This is the area direction off area off Quite grew. The direction off magnetically in good one is I love this. This is why mixes. And this is their direction. So we hunt there, dear is a tangle of 90 dd between idiot and Matic. So then Gettys 90 in this guest. No, putting our news here. Flux is the local be course. Oh, Mind E and the girls off. Monty is the local hero. So no Dick Clark's true quite doing mi quarto may. Hey, my like my little and this is close to zero. So this is the When I take loves that well, who will be zero because it is held or is entirely while the quail one is held? Uh, what bigger? And, uh, no clubs passes through the quail. Go is this area is about a pending blood to the men etiquette off quite one. So resulting in a degree off 90 degree, which makes amenity clocks through the quad school equals zero. Thank you, but watching

Belongs to the electromagnetic induction in which we have a conductor having conductance L equals to 1 20 million Henry. That is equal to 0.1 to zero Henry. And over what time you must increase the current. So we have to calculate here delta T. And the changing current Delta is equal to 3.0 ampere. And the induced EMF is equal to 6.0 volt. So for the conductor coil we know that the induced EMF. Excellent. It is equal to L. D. By D T. So we can write it as Elmer player by delta I, delta I delta T. So from here after rearranging we get delta T. That is equal to Elmore played by delta I developed by Excellent. Okay, so substituting values so we get L. Which is 0.1 to zero Henry. But the plan Delta II which is 3.0 M. Pierre de Barbie induced D M F. Which is 6.0 volts. So from here after solving we get delta T. That is equals to 0.6 seconds. Okay, so this becomes the answer for this question. Okay

To the electromagnetic induction in which we have number of tons and equals 2-40 and carrying current I equals to 3 50 million M. Pierre. That is equal to 0.350 mps. Okay if the magnetic flux through the coil is five equals to 0.75 waiver. Then we have two coil calculate the coils inductions. That is help. Okay, so we know that the netflix and five. This is equals two L manipulated by from the theory of self induction. So from here we get self induction help equals two N five divided by current. I So substituting values so we get L equals two and which is to 40 multiplied by five which is 0.75 Weber developed by current high which is 0.350 mps. Okay, so from here after solving we get inducted of the coil help. That is equal to 514.3 Henry. Okay, so this becomes the answer for this question. Okay.
