for radiation therapy A cyclotron is a type of particle accelerator in which charged particles accelerate outwards from the center along a spiral path. The particles are held to a spiral trajectory by a static magnetic field and accelerated by a rapidly varying (radio frequency) electric field. History[edit] The cyclotron was invented and patented[1] by Ernest Lawrence of the University of California‚ Berkeley‚ where it was first operated in 1932.[2] A graduate student‚ M. Stanley Livingston‚ did

3.3.3 In Class or Homework Exercise 1. The rectangular loop below is being pulled to the right‚ out of the magnetic field which points inward as shown. In what direction is the induced current? No current is induced in the top or bottom wire‚ since they are moving parallel to themselves. The only current induced is in the left wire‚ where the current is induced upward. The result will be a clockwise current. 2. If the solenoid below is being pulled away from the loop shown‚ in what direction

Recent models have made use of excitonic states but have emphasized either the charge or spin characteristic of the gap. According to

HARD AND SOFT MAGNETIC MATERIALS: Materials‚ which are difficult to magnetise and de-magnetise. Soft materials are easy to magnetise and de-magnetise. MAGNETIC FIELD: The area around a magnet where another magnet would feel a force. MAGNETIC FIELD LINES: Show the direction of the magnetic field. The lines run from North to South. Where the field is strong‚ they are close together. INDUCED MAGNETISM: A magnetic material can be magnetised by being placed in a magnetic field. ELECTROMAGNET:

distribution of magnetic flux lines when the iron ring was placed in between the U-magnets? The distribution of magnetic flux lines when the iron ring is placed in between the magnets‚ the iron ring is included in the distribution of flux lines. Instead of connecting to the other pole‚ the ring affects its distribution and some of it is attracted to the iron ring. 2. How does changing the current affect the magnetic force on a wire suspended in a magnetic field? As the current rises‚ the magnetic force

FACULTAD DE SISTEMAS DC Motors Catedrático: Ing. Gustavo Mendoza Leal Alumno: Alfredo Valdés Cárdenas Introduction A DC motor is a type of electrical machine that converts direct current into mechanical power by means of a magnetic field. DC motors are widely used in field applications because of their many advantages over AC motors such as speed control‚ high starting torque‚ quick starting‚ stopping‚ reverse and acceleration and free from harmonics found in AC. Applications of DC motors include

theorems‚ as well as a reminder of the differential equation that describes wave motion. The two mathematical theorems that we need to remind ourselves of are: The surface integral of a vector field over a closed surface is equal to the volume integral of its divergence. The line integral of a vector field around a closed plane curve is equal to the surface integral of its curl. There are four basic equations‚ called Maxwell equations‚ which form the axioms of electrodynamics. The so called local
