Correlation Electromagetism Energy Magnetic field Potential Potential energy Torque

AI Thread Summary

The discussion centers on the equations U=-μ⋅B for potential energy and τ=μ×B for torque, where μ represents the magnetic moment defined as μ=IA. Participants seek clarification on the meaning of μ and its role in interpreting the relationship between potential energy and torque in electromagnetism. The connection indicates that as the magnetic moment interacts with the magnetic field, it influences both potential energy and torque. Understanding these equations is crucial for grasping how magnetic moments operate in magnetic fields. The conversation highlights the importance of comprehending the magnetic moment in the context of these physical principles.

In class while learning about electromagnetism, I was given the following two equations:
U=-μ⋅B
τ=μ×B
where μ=IA
First of all, what does μ stand for?
How should I interpret the relationship between potential energy (U) and torque? Can someone explain this in terms of μ and B?

Oh boy, did you fall asleep during the first part of the class on magnetic moment ?

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
