What is the shape of an electric field?

The electric field is radially outward from the point charge in all directions. The circles represent spherical equipotential surfaces. The electric field from any number of point charges can be obtained from a vector sum of the individual fields.

How do electric and magnetic fields affect moving charged particles?

The motion of a charged particle in the electric and magnetic field. In case of motion of a charge in a magnetic field, the magnetic force is perpendicular to the velocity of the particle. So no work is done and no change in the magnitude of the velocity is produced (though the direction of momentum may be changed).

What happens to a moving charged particle in a magnetic field?

A charged particle experiences a force when moving through a magnetic field. 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.

What happens when a charged particle moves in an electric field?

In an electric field a charged particle, or charged object, experiences a force. If the forces acting on any object are unbalanced, it will cause the object to accelerate. If two objects with the same charge are brought towards each other the force produced will be repulsive, it will push them apart.

What is magnetic field direction?

• The direction the magnetic field produced by a. moving charge is perpendicular to the direction of motion. The direction of the force due to a magnetic field is perpendicular to the direction of motion.

What is the shape of an electric field around a negative charge?

Given a point charge, or a particle of infinitesimal size that contains a certain charge, electric field lines emanate radially in all directions. If the charge is positive, field lines point radially away from it; if the charge is negative, field lines point radially towards it.

Can magnetic field do work on moving charge?

A constant magnetic field does no work on a moving charge particle because the force on moving charge particle due to the magnetic field is always perpendicular to the displacement of charge particle.

How does a charge move in an electric field?

A positive charge placed in an electric field will tend to move in the direction of the electric field lines and a negative charge will tend to move opposite to the direction of the electric field lines.
