Why does a magnetic field exert a force on a moving electron?

Under certain conditions, electric current causes a magnetic field. A moving charged particle creates a magnetic field around it. Additionally, when a moving charged particle moves through a different magnetic field, the two magnetic fields will interact. The result is a force exerted on the moving charged particle.

Why does a force act on charge only when it moves in magnetic field and not when it is at rest?

Because the magnetic field acts perpendicular to a charges instantaneous direction of motion (at right angles to its motion). Therefore if a charge is not moving, there is no perpendicular force asserted.

Does electric field exerts force on moving charge?

Electric field exerts force on both stationary and moving charge. Magnetic field exerts force on charge moving parallel to the direction of the field.

Why do magnetic fields exert forces?

Magnets exert forces and torques on each other due to the rules of electromagnetism. The forces of attraction field of magnets are due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the material.

Does magnetic field exert force on a charged particle?

Magnetic fields exert forces on charged particles in motion. The direction of the magnetic force F is perpendicular to the plane formed by v and B as determined by the right hand rule.

Can magnetic forces act on stationary charges?

A charge placed in a magnetic field experiences a magnetic force. 1. The charge must be moving, for no magnetic force acts on a stationary charge.

Does a magnetic field exerts a force on a moving charge in the same direction as the direction of field itself?

A magnetic field exert a force on a moving charge in the same direction as the direction of field itself.
