Can you accelerate a stationary charged particle witha magnetic field or an electric field and please explain?
Misomiso
Yes.
You must understand that magnetic fields induce electric fields 90 degrees out of phase (or perpendicular) to them, and vice versa.
A charged particle will want to move one way or another when put within an electric / magnetic field, because the field will provide a push or pull on that particle in a specific direction.
The easiest physical way to view this is with two magnets - imagine a small stationary magnet. If you take another magnet and hold it close to the stationary magnet, the second magnet will be creating a magnetic field that will either push the stationary magnet away or draw it closer. The same thing can be done by creating an electromagnet (push current through a coil of wire near the stationary magnet).

How did JJ Thomson know that the particles in the cathode-ray tube were negatively charged?
They are found to be deflected by electric and magnetic field in the specific direction in which a negatively charged particle would get deflected.
Are particle accelerators the same as super colliders?
Sort of. Particle accelerators are anything that take particles (usually electrons or protons) and accelerate them to high speeds. Super colliders are really powerful particle accelerators along with a bunch of equipment to measure what happens when the particles collide. So when someone talks about a particle accelerator, they're usually talking about colliders. But there are lots of things that are particle accelerators that aren't colliders. The old CRT computer monitors (heavy ones that are about as deep as they are wide) accelerate electrons and shoot them into the glass plate in front to make light, so there's a particle accelerator inside.
What are the non destructive tests for welding?
Magnetic Particle Testing, Ultrasonic Testing, Dye Penetrant, Radiography Testing (x-ray), Visual Inspection
What is the basic unit of charge?
The SI derived unit of electric charge is the coulomb(C).In electrical engineering, it is also common to use the ampere-hour (Ah).In chemistry and particle physics, it is common to use the elementary particle charge (e) as a unit.Independent of units, the symbol Q often denotes charge.
Why is magnetic force 0 if angle between current flow and magnetic field is 0?
One answer to this is that there is no answer; it is just a fundamental property of, or equivalently part of the definition of, a magnetic field that it produces a force on a charged particle perpendicular to both the field and the particle's velocity. (Though the existence and properties of the magnetic field can be derived from the electric field in relativity.) However, if you're so inclined, this can also be seen by an argument from symmetry and energy conservation. Let's say there is a magnetic field parallel to a current flow, and let's say there's a force on the flowing particles which can be predicted mathematically from the field. Which direction is it in? By symmetry it must be either with or against the current. All directions perpendicular to the current and field are the same; there's no physical law that could choose between them. This also means the field is either doing work on the current or having work done on it. So which is it? Now consider how that magnetic field is generated. It must be generated by another current flowing perpendicular to the first one. Let the two currents be the same. Now we see that by a reflection and a rotation the two currents are interchangeable. So, if each generates a force on the other, either both the currents are doing work or both are having work done on them; either way this violates energy conservation and cannot be.
What are electric and magnetic properties of particle?
w What are electric and magnetic properties of particle?
Distinguish an electric from a magnetic field?
An electric field can created by a presence of a charge particle such as electron or proton. While a magnetic fieldis created due the relative motion of a charge particle with repeat to a stationary observer, motion of the charge particle.
Which are defected by electric and magnetic fields?
Any charged particle in motion especially not parallel to the magnetic field, current carrying conductor kept inclined or perpendicular to the magnetic field would get deflected. As far as electric field is concerned, even stationary charges would be displaced.
What are three things that a magnetic field may do to moving charged particles?
Accelerate the particle but not beyond C, the speed of light Decelerate the particle Divert the particle's path.
What happens to a charged particle at rest in the magnetic field Does the particle accelerate?
The particle stays at rest a= f/m = 0; because force = qvB is zero if v=0.
What particle can not be accerlated by the electric or magnetic field in a particle accelerator?
The ones that have more mass than the accelerator can move.
What makes electromagnitc radiation?
an accelerating charged particle or synchronized electric and magnetic fields
Light possesses two properties?
Light possesses both properties of a wave and a particle. As a wave it is an oscillating electric and magnetic field. As a particle, light is a packet of energy that is treated as a point particle that does not have an electric field without a charge.
What does magnetic mean in science terms?
A magnetic field is a field of force produced (1) by moving electric charges, (2) by electric fields that vary in time, and (3) by the intrinsic magnetic field of elementary particles associated with the spin of the particle.
How is a charged particle accelerated when the electric field inside the dees of a cyclotron is zero?
it is the magnetic field not the electric field which accelerates the ion inside the dees
Every charged particle produces a?
It produced a magnetic field. If it's charged, it can be negative OR positive. It's magnetic because if they're both alike signs (both positive or both negative) they repel like magnets. If one particle is positive and one is negative, they attract like magnets.
Does a particle need to have an electrical charge to be used in a particle accelerator?
Yes, a particle used in a particle accelerator must have a charge to be useful in the device. Particle accelerators we use in high energy physics to investigate things all work by applying a moving or shifting magnetic field to accelerate charged particles. We speed these particles up by repeatedly "hitting" them with a magnetic field. Uncharged particles will not respond to this, and canot be used in the devices.
