Moment Ring

AI Thread Summary

A 20 A current flows through a ring with a diameter of 30 cm, raising the question of the moment affecting the ring. The discussion highlights the assumption that the ring's magnetic field is responsible for the moment, as no external magnetic field is mentioned. Participants question whether the ring is in a magnetic field, specifically the Earth's magnetic field. The focus remains on calculating the moment generated by the current in the ring. The conversation emphasizes the need for clarity on external influences to accurately determine the moment.

Is the ring in a magnetic field? The Earth's magnetic field?

There's no mention of any outside magnetic field. So I'm assuming the ring's magnetic field is creating the Moment.

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'How to find eddy current (circular) path in this pendulum experiment?'

Does the direction my second finger points in indicate the literal direction of magnetic field at that point in space, or do I need to further use right hand rule or something for a circular path around the finger
