Summary: Can a particle accelerator accelerate gaseous fuel?
Does space-time differ for detonating ionized fuel moving near the speed of light within a magnetic field such as a particle accelerator?
For the front wire, I got the magnitude of the magnetic field in terms of the magnitude of the magnetic force, the current, "l," and the "theta". I am unsure how to proceed because I thought that the magnetic force is independent of any other forces. I am also just lost in general. Any help...
After carefully reading text books, research papers and a lot of forums, I find myself more confused than ever regarding the composition of magnetic fields. So please let me ask some (hopefully) very simple questions:
(1) Do we or do we not know exactly how magnetic fields arise and dissipate...
I might be a slow learner, but am still trying to understand the difference between field lines and vectors.
I've got that magnetic field lines are symbolic and that the directional arrows applied (from north to south) are a convention.
But see the attached image. The field lines form a closed...
I am trying to derive the equation ##\vec{\Gamma} = \vec{m} \times \vec{B}##, where ##\vec{m} = I \vec{A}## is the magnetic moment, and ##\vec{A}## is normal to surface ##A##, from the Lorentz force law ##\mathrm{d}\vec{F} = I \vec{dl} \times \vec{B}##. For an arbitrary closed current loop ##C##...
If an electron is moving in a circle in a magnetic field, it produces a magnetic field in accordance to the right hand rule. If a proton is moving in a circle in a magnetic field, would it produce a magnetic field in accordance to the left hand equivalent to the right hand rule.

Hello all.
Me and some friends are building a coil cannon, and we've been doing some calculations [I know its unecessary but... well, we're physicists! (well, physics students...)]. But we got stuck.
How to calculate the force acting on a steel bar (or some other ferromagnetic material, maybe...
I have this question which I need to solve . But I am unable to.
Suppose I have a current ring of radius R and current I (constant).
at a distance x from the centre of the ring, I have a iron disk (radius r and thickness t) present in the plane of the ring. This disk will be attracted to the...

A proton is accelerated from rest at the positive plate of two charged parallel plates with a potential difference of 2000 v. After leaving the plates through a small hole in the negative plate, it enters a uniform magnetic field of 0.50 T in a direction perpendicular to...

A single ionized uranium ion of mass 6.9 x 10 ^-25 kg is accelerated through a potential difference of 4.4 x 10^5 V.
What is the radius of the path it would take if injected at 90 degrees into 0.47 T uniform magnetic field at this velocity?

Hello,
As a heuristic tool for a complex problem, I'm trying to understand a series of nested conducting loops each with a initial identical current on it. These perfectly conducting loops are in the same plane each with that current in either direction. Each nested loop is perfectly...
