## What is magnetic Lorentz force Class 12?

Solution : When an electric charge q is kept at rest in a magnetic field , no force acts on it. At the same time, if the charge moves in the magnetic fieldm, it experiences a force is difference from Coulomb force. This force is known as magnetic Lorentz force.

## Is Lorentz force same as magnetic force?

The Lorentz force describes the force calculated using electromagnetic theory, it is the same thing as the electromagnetic force.

What does Lorentz law state?

The Lorentz force law states that a magnetic field exerts a force on a moving ionic current. 3. The Hall effect further states that when a magnetic field is placed perpendicular to the direction of flow of an electric current, it will tend to deflect and separate the charged ions.

### What causes the Lorentz force?

The Lorentz Force is the force on a charged particle due to electric and magnetic fields. A charged particle in an electric field will always feel a force due to this field, of magnitude F, equals, q, E,F=qE.

### How do you find Lorentz force?

Lorentz force is determined by the formula F = qv x B, in which q is the charge, v is the velocity, and B is the magnetic field density. Lorentz force is perpendicular to both velocity and magnetic field. The right hand rule is applied when determining Lorentz force.

What is the effect of the Lorentz force?

We have shown that Lorentz force can enhance mass transport in electrochemical reactions. This effect is called the magnetohydrodynamic (MHD) effect and is caused by magnetic forces which induce convective movements in the electrolyte. Figure 1: Schematic of movement of a charged particle in magnetic field.

## What is unit of Lorentz force?

In SI units, the magnetic field does not have the same dimension as the electric field: B must be force/(velocity × charge). The SI unit of magnetic field is called the Tesla (T): the Tesla equals a Newton/(coulomb × meter/sec). To convert: 1 T = 104 G.

## How do you calculate magnetic force?

Magnetic Force

1. The force is perpendicular to both the velocity v of the charge q and the magnetic field B.
2. The magnitude of the force is F = qvB sinθ where θ is the angle < 180 degrees between the velocity and the magnetic field.
3. The direction of the force is given by the right hand rule.

Where is the Lorentz force used?

Cyclotrons and other particle accelerators use Lorentz force. A bubble chamber uses Lorentz force to produce the graph for getting the trajectories of charged particles. Cathode ray tube televisions use the concept of Lorentz force to deviate the electrons in a straight line so land on specific spots on the screen.

### How do you find the Lorentz force?

Lorentz force is determined by the formula F = qv x B, in which q is the charge, v is the velocity, and B is the magnetic field density. Lorentz force is perpendicular to both velocity and magnetic field.

### What unit is magnetic force?

Tesla
The standard SI unit for magnetic field is the Tesla, which can be seen from the magnetic part of the Lorentz force law Fmagnetic = qvB to be composed of (Newton x second)/(Coulomb x meter). A smaller magnetic field unit is the Gauss (1 Tesla = 10,000 Gauss).
