## What happens to a charged particle when it moves perpendicular to a magnetic field?

As the direction of the particle changes, its momentum also changes. So, when the velocity of the particle is constant its energy will also remain constant. Thus, we can say, when a charged particle moves perpendicular to the uniform magnetic field, then the momentum changes while the total energy remains the same.

### Is any work done by a magnetic field on moving charge perpendicular to the magnetic field?

No work is done by the magnetic field on the moving charge.

#### What force is experienced by a charge moving perpendicular to the magnetic field?

Magnetic Forces on Moving Charges The magnetic force on a free moving charge is perpendicular to both the velocity of the charge and the magnetic field with direction given by the right hand rule. The force is given by the charge times the vector product of velocity and magnetic field.

**What happens to the magnetic force on an electron moving perpendicular to the direction of a magnetic field if the speed of the electron increases?**

The magnetic field does no work, so the kinetic energy and speed of a charged particle in a magnetic field remain constant. The magnetic force, acting perpendicular to the velocity of the particle, will cause circular motion.

**How does a charged particle moves in crossed electric and magnetic field?**

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. The perpendicular force, q v × B, acts as a centripetal force and produces a circular motion perpendicular to the magnetic field.

## How does a charged particle move in an electric field?

In an electric field a charged particle, or charged object, experiences a force. If two objects with opposite charges are brought towards each other the force will be attractive, it will pull them towards each other.

### What is work done by a magnetic field on a moving charge and why?

zero because →F acts parallel to →v.

#### What is the work done by a magnetic field on a charged particle?

Work done by uniform magnetic field on charge particle is zero. Force, magnetic field and velocity are mutually perpendicular to each other.

**Why do magnetic fields exert forces on moving charges?**

There is no magnetic force on static charges. However, there is a magnetic force on moving charges. When charges are stationary, their electric fields do not affect magnets. But, when charges move, they produce magnetic fields that exert forces on other magnets.

**Is it possible for the magnetic force on a charge moving in a magnetic field to be zero?**

b) no, it is not possible for the electric force on a charge moving in a electric field to be zero because in the case of the electric field, the particles velocity or motion has no bearing on magnitude or the direction of the electric field.

## Why magnetic field does no work on moving charge?

Magnetic force is always perpendicular to velocity, so that it does no work on the charged particle. The particle’s kinetic energy and speed thus remain constant. The direction of motion is affected, but not the speed.

### How does a charged particle move in 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 force does a magnetic field exert on another moving charge?

Magnetic fields exert forces on other moving charge. The force a magnetic field exerts on a charge q moving with velocity v is called the magnetic Lorentz force . It is given by It also is perpendicular to the direction of the velocity v. ( Review the vector or cross product!)

**Why is the magnetic force perpendicular to the motion?**

Q & A: why is the magnetic force perpendicular to the motion. The superficial answer is simply that the Lorentz (magnetic) force is proportional to v × B, where v is the particle velocity and B is the magnetic field. Since the vector cross product is always at right angles to each of the vector factors, the force is perpendicular to v .

**Can a charge be attracted by a permanent magnet?**

If you consider a “pure” electric point charge without any further characteristics such as a magnetic moment etc., then it IS NOT attracted by a permanent magnet. Only if it is moving, the Lorentz force will act perpendicular to the moving direction. If, however, you consider a (ferromagnetic) metal then it will experience a force.

## Why is the force of a charged particle maximum when moving?

Hence the charge particle moving parallel or anti-parallel to the direction of magnetic field experiences no force. Hence force experienced by the charged particle is maximum when it is moving perpendicular in the direction of magnetic field.
