Effects of Placing a Compass Under a Cable

AI Thread Summary
Placing a compass directly under a cable can affect its reading due to the magnetic field generated by the current flowing through the wire. The impact on the compass depends on factors such as the type of cable and the amount of current it carries. A wire with a significant electrical current can create a magnetic field strong enough to influence the compass needle. Understanding how a compass works and the nature of the cable is essential in determining the extent of this effect. Overall, the compass may show deviation when positioned under a current-carrying cable.

Homework Statement


If we put a compasd UNDER a cable..

Will that effect on the compass ?


I WANT THE ANSWER AS SOON AS POSSIBLE


Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
Maybe, maybe not.

Depends.
 
depends on what ?! :confused:
 
What sort of cable? What is happening with the cable?

How does a compass work?

Why might whatever is happening affect a compass?
 
What sort of cable? What is happening with the cable?
A wire, and the current go over it ..


NOTE THAT THE COMPASS IS UNDER THE WIRE NOT NAER IT
 

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 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
