Detailed explanation-1: -It requires electrons and protons to produce a magnetic field. As the electrons move relative to protons (ions) there is a relativistic charge per unit volume difference between the positive and the negative charges. This causes any external charges to feel a force we know as the magnetic field.
Detailed explanation-2: -Spinning like tops, the electrons circle the nucleus, or core, of an atom. Their movement generates an electric current and causes each electron to act like a microscopic magnet. In most substances, equal numbers of electrons spin in opposite directions, which cancels out their magnetism.
Detailed explanation-3: -This magnetic force acts as the centripetal force on the charged particle. So, the charged particle will move in a curved path in the magnetic field. The particle will move in the curved path and will form a circle. So, when the electron moves in the transverse magnetic field its path becomes circular.
Detailed explanation-4: -Yes because : A moving charge or electric current is the source of the magnetic field. Therefore, A moving charge or current-carrying conductor induces a magnetic field around it. An electron is a charged particle having a charge equal to.
