When an electric field is applied to moving electrons in space, the field exerts a force on the electrons due to their charge. This force causes the electrons to deviate from their original path and change direction. The amount of deflection depends on the strength of the electric field and the velocity of the electrons.
What else can I help you with?
The behavior of cathode rays in a glass tube containing gas at low pressure led scientists to conclude that the rays were composed of?
Electrons. The behavior of cathode rays, such as being deflected by electric and magnetic fields, matched the properties of electrons. This discovery by J.J. Thomson in the late 19th century ultimately led to the identification of electrons as subatomic particles.
How do moving electric charges and magnets interact?
Moving electric charges produce a magnetic field, which can interact with other magnetic fields, including those produced by permanent magnets. This interaction can result in forces being exerted on the moving charges and/or the magnets, leading to phenomena such as magnetism, electromagnetic induction, and electric motors.
What particle can not be accerlated by the electric or magnetic field in a particle accelerator?
Neutrinos cannot be accelerated by electric or magnetic fields in a particle accelerator because they have no electric charge and very small magnetic moment. This means they are unaffected by these fields and pass through them without being deflected.
Are the free moving electrons in metals account for many of the properties of metals?
Yes, the free-moving electrons in metals are responsible for many of their properties. These electrons allow metals to conduct electricity and heat, be malleable and ductile, and exhibit luster. The delocalized nature of these electrons also contributes to metals being good conductors of electricity and heat.
Why are gamma rays not affected by a magnet as they pass over it?
Gamma rays are not charged particles, so they are not affected by magnetic fields in the same way that charged particles like electrons are. This is because electromagnetic fields mainly interact with charged particles due to their electric charge. Gamma rays are photons, which are electrically neutral, allowing them to pass through magnetic fields without being deflected.
Which rays are not deflected by electric or magnetic fields?
Neutrinos are not deflected by electric or magnetic fields because they have no electric charge and very weak interactions with matter. These properties allow neutrinos to travel through space without being affected by electromagnetic forces.
Explain why the atoms need to be ionized before element x atoms can be deflected in a mass spectrometer?
Ionizing the atoms of element x allows them to gain or lose electrons, creating charged particles. These charged particles can then be deflected by applying an electric or magnetic field in a mass spectrometer. Without ionization, the neutral atoms of element x would not respond to these fields and therefore cannot be effectively deflected for analysis.
Is a magnetic field surrounded by moving electric charges?
Yes, a magnetic field is generated by moving electric charges. When charged particles such as electrons are in motion, they create a magnetic field that can exert forces on other charged particles. This relationship is described by the magnetic field's direction being perpendicular to both the direction of motion of the charged particles and the electric field.
What can you conclude about the orientation of the beam relative to the magnetic field when a beam of electrons passes through a magnetic field without being deflected?
If a beam of electrons passes through a magnetic field without being deflected, then the orientation of the beam is perpendicular to the magnetic field lines. This is because the force acting on a charged particle in a magnetic field is always perpendicular to both the magnetic field and the velocity of the particle, causing the electrons to move in a circular path perpendicular to the field lines.

What is definition of electric current?
Current is the motion of electrons in a conductor being propelled by electromotive force (voltage).

Why does aluminum get hot fast?
Aluminum , being metal, has free moving electrons which transfers heat and electricity very quickly.
When a battery runs a motor what energy is changed to what energy?
electric to mechanical/kinetic energy the electrons are not actually changed and used, it is important to know that (even if you do, it's worth mentioning if someone happens upon this article and doesn't). The energy that is being converted that is electrical is actually the pushing force on the electrons, the electrons moving through the copper wiring causes magnetic fields to form and creates attraction and displacement inside the motor.
