The presence of a magnetic field causes the path of an electron to curve, resulting in circular motion. This is due to the force exerted on the electron by the magnetic field, known as the Lorentz force.
The strength of the magnetic field directly affects the radius of the electron's circular motion. A stronger magnetic field will result in a smaller radius, while a weaker magnetic field will result in a larger radius.
The velocity of an electron is perpendicular to its motion in a magnetic field. This means that the electron will constantly change its direction of motion as it moves in a circular path.
Yes, an electron's motion can be affected by multiple magnetic fields. In this case, the electron's path will be a combination of circular motions due to each individual magnetic field.
The direction of the magnetic field determines the direction of the force exerted on the electron. As a result, the electron's motion will be perpendicular to the direction of the magnetic field.
