Magnetic Field Strength in a Solenoid at t = 1 ms

AI Thread Summary
The discussion focuses on determining the magnetic field strength inside a solenoid at t = 1 ms. Initially, there is confusion regarding the difference between electromotive force (emf) and magnetic field strength. It is clarified that emf is not the same as the magnetic field. After some deliberation, the participant discovers the relevant equation for the magnetic field of a solenoid and calculates the magnetic field strength based on the inductor's current at the specified time. The thread concludes with a successful application of the formula to find the magnetic field strength.

Homework Statement



What is the magnitude of the magnetic field inside the solenoid at t = 1 ms?

Homework Equations



Not sure

The Attempt at a Solution



Well I would make an attempt but firstly I have a question. What I want to know is the above question simply referring to the emf of the solenoid? Is the emf the same thing as the magnetic field? I cannot seem to find an equation relating magnetic fields and inductors.

No, it is asking about the strength of the magnetic field, which is not the same as the emf.

Right moments after posting this I found an equation for the B of a solenoid. I then found i for the inductor based on the given time and was able to find the stregth of B from that.
 

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...
