Thanks so much

Curious, did it save your grade?

yes actually! solid B in the practical portion

This is true. However the concept of relativistic energy is used instead, where E(rel) = m(rel)c^2 this is a better description of what is happening. Unfortunately, A-level specifications tend to hold on to older concepts for a while :)

To be sure

Hope the exam went well

You are absolutely right. So sorry for the mistake. That makes the induced emf 0.126V instead of 126. In an exam this would be a penalty of 1 Mark for a power of 10 error 😭

The best thing, in my experience, is to practice drawing results tables (putting in spaces for repeats and averages) and ensuring that your decimal places / significant figures are consistent. Then think on what experiments can be asked from your specification and what measurements you would like to take. If you can get some lab time that would be great but even videos of experiments are good. You want your exam to ideally be something you have seen before.

Going to frame this comment....or at least add it to my CV

Thanks so much. I've had a bit of time on my hands!

Yea this is a bot

If you plotted T against l it would be a curve. But if T^2 is proportional to l then plotting T^2 against l will give a straight line (that's what proportional always gives). Does that make sense?

Hi. You are right, mathematically if you had 2 magnets that provided the same force on the same length of wire than the on that could do that with the Least current would be the stronger magnet and have greater field strength. However we generally consider the absolute force F, acting on an object which depends directly on more field strength (stronger magnet), more length and more current will provide the greatest actual force. I think you might be confusing magnetic field strength B with the force acting F at a conceptual level. Does that help or have I missed the point of your question?

@@PhysicsRocksItsTrue sir can u explain in simple language

The equation is for a current flowing through a magnetic field so the field is created by the magnet and the current is produced by a power supply connected to a wire. So they are separate things. If I increase the current the force will increase but the length of the wire will not change, nor will the strength of the magnet. If I replace the magnet with a more powerful one then the force will increase but the current and length of wire will not be affected. So what I'm saying is that F is affected by B I and L but B is affected by them. Is that more clear?

@@PhysicsRocksItsTrue ok, I see, thanks for replying!

Awesome. Hope the videos are helpful

That's a good question. I would like to if I can get back into my work lab. Watch this space!

PhysicsRocksItsTrue Cool

Absolutely. Will probably do one this week

Haha didn't even notice.. The danger of live TV. I assure you that it's a fact!

True...really glad I did it now!

I assume the sigma amplitude =0 is because it would follow a normal probability distribution?

Thanks so much

Thanks so much, this is the type of comment that makes it worthwhile prepping these lessons!

Likely you'll be hearing a lot from me in the coming weeks
