The magnetic force will not change the speed of a moving electron because the magnetic force is always perpendicular to the velocity. A moving electron in a uniform magnetic field will undergo uniform circular motion.
Q. Why does the kinetic energy of a charged particle moving in a magnetic field remains constant?
When a charged particle moves in a magnetic field, does its kinetic energy always remain constant? This means that a uniform magnetic field can do no work on charged particle although it can change its direction of motion. Hence the kinetic energy of charged particle in a magnetic field remains unchanged.

Q. Can a charged particle move through a magnetic field without experiencing any force?
So, Charge particle does not experience any force when it is moving parallel to the uniform magnetic field as v and B will be in same direction.
Q. Can an electron at rest in a stationary magnetic field be set into motion by the magnetic field what about the electron placed at rest in an electric field?
An electron at rest in a magnetic field experiences no force, so cannot be set in motion by the magnetic field. If it were placed at rest in an electric field, it will accelerate under the electrostatic force.
Q. Are the hanging paper clips moving at rest?
Answer. Answer: because it is not moving. cliffffy4h and 4 more users found this answer helpful.
Q. Are the forces acting on the paper clips hanging in the wall?
yes,there are force acting on the hanging paper clips ,tension force and gravitational force.
Q. What happens to the hanging paperclips?
It isn’t falling, and so it forces the object to stay with it, balancing (and reacting to) the gravitational force pulling downwards on the object, causing the object to remain suspended and in an equilibrium (it’s not accelerating; in this case, the object is still or ‘at rest’ and is not starting to move.
Q. What could have caused the motion of the hanging paper clips?
Answer. Answer: The paperclip will float due to surface tension. Surface tension is the attraction of like particles to one another on a surface—in our case, a water-air surface.
