What happens when electron enters parallel to magnetic field?
What happens when electron enters parallel to magnetic field?
Charged particles move in straight lines at a constant speed if projected into a magnetic field along the direction of the field. If the electron enters the field at an angle to the field direction the resulting path of the electron (or indeed any charged particle) will be helical as shown in figure 3.
How do you determine direction of deflection?
It states that, to determine the direction of the magnetic force on a positive moving charge, you point the thumb of the right hand in the direction of v , the fingers in the direction of B , and a perpendicular to the palm points in the direction of F .
What is deflected distance?
In engineering, deflection is the degree to which a structural element is displaced under a load (due to its deformation). The deflection distance of a member under a load can be calculated by integrating the function that mathematically describes the slope of the deflected shape of the member under that load.
In which direction does the magnetic field in the center of the coil point?
The standard right hand grip rule can be modified to predict the direction of the magnetic field. If the right hand fingers curl round the coil in the direction of the current, then the thumb points in the direction of the magnetic field down the centre of the coil.
What is the direction of electron in magnetic field?
The direction of the force acting on the electron is the direction the palm of the left hand faces. The direction of the magnetic field, the direction of the moving charge, and the direction of the force on the particle are all perpendicular to each other.
What is the direction of electron in a magnetic field?
What is deflection in a magnetic field?
Magnetic deflection (Fig. Magnetic coils are placed in pairs on the outside of the CRT to provide horizontal and vertical magnetic fields perpendicular to the electron flow. Current in these coils causes deflection of the electrons perpendicular to the magnetic field and to the direction of the electrons.
