Introduction: The Large Hadron Collider Valerie Jamieson-New Scientist Large Hadron Collider “Actually Worked” Mason Inman-National Geographic Maneesha Wijesinghe In 1909‚ at a small laboratory at the University of Manchester‚ James Rutherford shot alpha particles at a gold nucleus which in result unveiled the legendary discovery of the structure of the atom. Exactly seventy years later scientists and engineers at the European Organization for Nuclear Research (CERN) launched the Large

| | | | | | | | | | | The direct current (DC) motor is one of the first machines devised to convert electrical power into mechanical power. Permanent magnet (PM) direct current converts electrical energy into mechanical energy through the interaction of two magnetic fields. One field is produced by a permanent magnet assembly; the other field is produced by an electrical current flowing in the motor windings. These two fields result in a torque which tends to rotate the rotor. As

passion. First of all‚ I will define passion; passion is more than an act that an individual enjoys‚ passion is enthusiasm‚ it’s obsession‚ it’s an act that you can repeat over and over again and never be unpleased.

1. Motors use the effect of forces on current-carrying conductors in magnetic fields Discuss the effect on the magnitude of the force on a current-carrying conductor of variations in: The strength of the magnetic field in which it is located • The magnitude of the force is proportional to the magnetic field strength. Thus‚ an increase in magnetic field strength will cause an increase in the force on the wire and a decrease in magnetic field strength will cause a decrease in force on the

enrolling in Magnet and taking AP classes‚ I feel like I am taking advantage of significant educational opportunities. These educational opportunities provide me with sources and insight of my college years to come. They also prepare for what I will be doing in my future. When I heard of the Magnet Program at Sylmar High School from my family members that have previously graduated from there‚ I knew I had to apply. With the alumni from magnet ranging from Stanford to Harvard I knew the Magnet Program
