When a magnetic field is applied to an electron at rest?
3) Can an electron placed at rest in a magnetic field be set in motion by the magnetic field? What if were 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.
When magnetic field is applied to a moving electron then in which direction the force is applied on electron and by which rule?
Right Hand Rule: Magnetic fields exert forces on moving charges. This force is one of the most basic known. The direction of the magnetic force on a moving charge is perpendicular to the plane formed by v and B and follows right hand rule–1 (RHR-1) as shown.
What is the magnetic field of a charged particle at rest?
Electric charges at rest in a magnetic field do not feel a magnetic force. where φ is the angle between v and B. So that, when v is parallel to B (φ = 0) or antiparallel to B (φ = 180o) then sinφ = 0 and FB = 0. Therefore, charged particles moving along magnetic field lines experience no magnetic force.
When a magnetic field is applied in a direction perpendicular to the direction of cathode rays?
Since force being perpendicular to direction of motion, Energy and magnitude of momentum remains constant. Cathode rays are moving along the positive Z-axis.An electric field is applied along positive Y-axis. In the same region, a magnetic field is also applied. The cathode rays pass undeviated in this region.
How current is loop in magnetic field?
According to Fleming’s left-hand rule, the magnetic force on sides PS and QR are equal, opposite, and collinear (along the sides of the loop), so their resultant is zero. Hence, A current loop in the magnetic field is in equilibrium in two orientations one is stable, and the other is unstable.
When an electron moves in a magnetic field in a direction perpendicular to the field then its path will be?
1). If the field is in a vacuum, the magnetic field is the dominant factor determining the motion. Since the magnetic force is perpendicular to the direction of travel, a charged particle follows a curved path in a magnetic field. The particle continues to follow this curved path until it forms a complete circle.
