Consider a moving neutron passing by an electromagnet, will a neutron be deflected? This video seem to show that the neutron would have to be charged in order for it to move
How? When?This video seem to show that the neutron would have to be charged in order for it to move
The video implies that the neutron would have to be charged at 2:44 The proton in the video moves because it is electrostatically repelled by the length contracted Protons in the wire. A neutron, being neutral, cannot experience this force.Simon Bridge said:How? When?
Note: Objects do not have to have a charge to be deflected by a magnet.

... see section on neutron spin: they are little magnets.
... directly after that, see the brute force measure for neutron neutrality.
"Objects do not have to have a charge to be deflected by a magnet." I was aware of this, I was just pointing out that the mechanism described in the video seems to imply that neutrons won't deflect, when they should, showing that the special relativity explanation is inconsistent with reality,Simon Bridge said:If a neutron were to experience the force being illustrated, then it would have to be charged. But there is nothing there to indicate that the neutron experiences the force being illustrated.
Basically you are noticing that the video is incomplete.
Did you read the link?
... or that the short introductory demo in a youtube video is somehow incomplete..."Objects do not have to have a charge to be deflected by a magnet."

I just thought so since they have magnetic moments,Simon Bridge said:... or that the short introductory demo in a youtube video is somehow incomplete...
BTW: what makes you think that neutrons deflect in the circumstances described in the video?
I'l say no, however, it must be deflected by permanent magnets which work on a different principleSimon Bridge said:Work it out - would a neutron, in the situation that the video places a proton, be deflected by the magnetic field of the wire?
You have to be careful not to overgeneralize small concepts. In the video they are specifically discussing the magnetic force on a point charge outside a current carrying wire. They are not even talking about the magnetic field. The magnetic force can always be made zero by transforming to a frame where the point charge is at rest, but that does not imply that the magnetic field is zero nor does it imply that the force on a magnetic dipole could be made zero.Danyon said:"Objects do not have to have a charge to be deflected by a magnet."

Neutrons in electromagnetic fields refer to the behavior and interactions of neutrons, which are subatomic particles, in the presence of electromagnetic fields. These fields can be created by electric charges or magnetic fields.
Neutrons do not have an electric charge, so they are not affected by electric fields. However, they do have a magnetic moment and are therefore affected by magnetic fields. The direction of the neutron's magnetic moment determines its behavior in the field.
Studying neutrons in electromagnetic fields is important for understanding the fundamental properties of neutrons and their interactions with other particles. It also has practical applications in fields such as nuclear physics, materials science, and medical imaging.
Neutrons can be used in medical imaging techniques, such as neutron radiography and neutron tomography. These methods use the interaction of neutrons with the body to create images that can reveal information about the internal structure and composition of tissues and organs.
Neutrons themselves do not pose a significant risk, as they are not ionizing radiation. However, if neutrons are used in nuclear reactions, they can produce secondary radiation that can be harmful. It is important to carefully control and shield these reactions to minimize any potential risks.
