Electromagnetic Electromagnetic induction Induction

AI Thread Summary

To calculate the magnetic field using electromagnetic induction, it's essential to start with the relevant equations, which include the current (I) and the length of the conductor (L). An angle of π/2 is needed for minimum magnetic field (B) calculations. The discussion emphasizes the importance of making an initial attempt at solving the problem before seeking assistance. By calculating the force (F) first, the magnetic field can then be derived. Understanding these steps is crucial for successfully applying electromagnetic induction principles.

Homework Statement: A .76 meter long wire runs horizontally and carries a current of 28A (left to right). What would be the magnitude and direction of the minimum magnetic field to suspend the wire in mid air if the wire has a mass of 46.6 g/m?

Relevant Equations: I think its F=ILBsin

gotta be honest I am really struggling

Hello mountain, ##\qquad## :welcome:

##\qquad## !

Unfortunately the PF guidelines require an attempt at solution before we are allowed to assist.

Your relevant equation is good (misses an angle at the end, but for minimum B an angle of ##\pi/2## does the trick).
So what is the problem ? You have I, L and you can calculate F. Then B follows !

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
