AI Thread Summary
The magnetic field direction at point P, located 0.040 m from a straight wire carrying a 5.0 A current to the left, is out of the plane of the page. Participants express confusion about determining the magnetic force direction, referencing Ampere's law without finding it helpful. Clarification on using the right-hand rule is suggested as a method to visualize the magnetic field's orientation. Understanding the relationship between current direction and magnetic field is essential for solving related problems. The discussion highlights the importance of mastering these fundamental concepts in electromagnetism.

1. A long, straight wire is carrying a current of 5.0 A in the direction shown in the
figure. The point P is 0.040 m from the wire.

What is the direction of the magnetic field at point P due to the current in the wire?

Answer: out of the plane of the page



I can only see that the current is to the left. I don't understand how to figure out the direction of the magnetic force. :(

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...
