## What is cyclotron in physics class 12?

A cyclotron is a machine that accelerates charged particles or ions to high energies. It was invented to investigate the nuclear structure by E.I. Lawrence and M.S. Livingston in 1934. Both electric and magnetic fields are used in the cyclotron to increase the energy of the charged particle.

What is cyclotron write its theory and working with diagram?

Cyclotron is a device used to accelerate charged particles to high energies. It was devised by Lawrence. Cyclotron works on the principle that a charged particle moving normal to a magnetic field experiences magnetic lorentz force due to which the particle moves in a circular path.

What is cyclotron with diagram?

A cyclotron is a device used to accelerate charged particles to very high speeds. A cyclotron consists of a metallic hollow cylinder divided into two parts called Dees. The two Dees have a gap between them where a source of ions is placed.

### What is cyclotron physics?

A cyclotron is a type of particle accelerator invented by Ernest O. The particles are held to a spiral trajectory by a static magnetic field and accelerated by a rapidly varying (radio frequency) electric field. Lawrence was awarded the 1939 Nobel Prize in Physics for this invention.

What is application of cyclotron?

Cyclotrons are widely used to accelerate charged particles in nuclear physics experiments and use them to bombard atomic nuclei. For radiation therapy in the treatment of cancer, different cyclotrons are used. Cyclotrons can be used for nuclear transmutation (change of the nuclear structure).

What is Laplace force?

When a wire carrying an electric current is placed in a magnetic field, each of the moving charges, which comprise the current, experiences the Lorentz force, and together they can create a macroscopic force on the wire (sometimes called the Laplace force).

## What is Lorentz force Class 12?

Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric field E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by F = qE + qv × B.

What is a solenoid class 12?

Solution. A solenoid is a long, insulated copper wire closely wound on a hollow cylindrical glass or plastic tube in the form of a helix. Concept: Magnetic Field of a Solenoid and a Toroid.

What is a Dee cyclotron?

In cyclotron. … two hollow semicircular electrodes, called dees, mounted back to back, separated by a narrow gap, in an evacuated chamber between the poles of a magnet. An electric field, alternating in polarity, is created in the gap by a radio-frequency oscillator. In particle accelerator: Classical cyclotrons.

### How many cyclotrons are there in India?

19 cyclotrons
There are 222 PET-CT, 3 PET-magnetic resonance imaging scanners, and 19 cyclotrons operating currently. India has witnessed relatively slower headways in terms of high dose radionuclide therapy facilities….

How many cyclotrons are there in the world?

There are over 1500 cyclotron facilities around the world, and the IAEA has recently updated its interactive map and database featuring 1300 of these cyclotron facilities from 95 countries.

How does a betatron work?

betatron, a type of particle accelerator that uses the electric field induced by a varying magnetic field to accelerate electrons (beta particles) to high speeds in a circular orbit. Modern compact betatron designs are used to produce high-energy X-ray beams for a variety of applications.

## Who is responsible for the CBSE syllabus for Class 12 physics?

How many units are there in Class 12 physics?

Also, the examinations will be conducted in two parts for each term. The Term 1 Physics Class 12 Syllabus will consist of four units, and Term 2 will cover five units.

What are the best physics projects for Class 12?

Electric Motor is one of the most common and basic projects that you can think of. Though the concepts involved in the motor are complex but making an electric motor is relatively easy. With just a requirement of a coil of wire, a magnet and a power source, it is a preferred choice for your Physics Project for Class 12 if you have limited time.
