A bit weird magnetism problem...

You see i have a problem... Assume the below situation in which there are 4 magnets above a wire and connected to a wheel of some sort. Now, once the wheel is in motion, Each set of the magnets have one strong and one weak magnet. In the first set, the strong magnet which is placed first, has north nearer to the wire than its south and in the weaker magnet the south nearer to the wire than the north. In the second set, its just the opposite... It's clear from the picture attached...Now the question is, if the wheel is put into motion... what is the resultant magnitude of the magnetic field with the wire in each turn that the magnets come near it and is there any current induced... if so what is it and finally if there is damping... what is it? The answer is asked only in terms of mathematical formulae...

I'm clueless...

P.S.

I'm sorry abt the picture quality... but i had real tough time uploading it... the file size was too large..., the picture was too big... eitherway.. i finally got it done...

Hey! How come no one's replied...? Isn't there nyone here who knows how to do this? If nyone knows... DOOOOOOOD / DOOOODET what r u waiting for?

This is definitely an interesting magnetism problem! It seems like there are a lot of variables at play here, so let's break it down step by step.

First, we have 4 magnets arranged in two sets, each set consisting of one strong and one weak magnet. The orientation of the magnets is also different in each set - in the first set, the strong magnet has its north pole closer to the wire while the weak magnet has its south pole closer, and in the second set, it's the opposite. This means that the magnetic fields from the two sets will interact differently with the wire.

Next, we have the wheel in motion. As the magnets on the wheel rotate, they will pass by the wire multiple times in each turn. This means that the magnetic field strength and direction will change as the magnets move closer and then further away from the wire.

Now, let's consider the effect on the wire. As the magnets pass by, they will induce a current in the wire. The magnitude and direction of this current will depend on the strength and orientation of the magnetic fields from the magnets, as well as the speed at which the wheel is rotating.

Finally, we have the question of damping - this refers to the decrease in amplitude of the magnetic field and induced current over time. This can be caused by various factors such as resistance in the wire, external magnetic fields, and the rotation of the wheel itself.

To answer the question about the resultant magnitude of the magnetic field and induced current, we would need to know more specific information such as the strength of the magnets, the speed of the wheel, and the properties of the wire. However, we can use mathematical formulae such as the Biot-Savart law and Faraday's law to calculate these values.

In conclusion, this is definitely a bit of a weird magnetism problem, but it's also a very interesting one! With more information and some mathematical calculations, we can definitely find the answers to the questions posed. Keep exploring and experimenting with magnetism - there's always something new to discover!
