Homework Statement
Is a current that produces a magnetic field always going to be either an electron or a proton?
What type of charges in currents produce a magnetic field?
Click For Summary
A current that produces a magnetic field is not limited to electrons or protons; it can also involve other charged particles such as muons. The key factor is the presence of electric charge, which is essential for generating a magnetic field when in motion. This principle applies to any charged particle, regardless of its type. Understanding the relationship between electric charge and magnetic fields is crucial in physics. The discussion emphasizes the broader range of particles that can create magnetic fields through current.
The answer is (B) but I don't really understand why.
Based on formula of Young Modulus:
$$x=\frac{FL}{AE}$$
The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A##
I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
