It is a type of scan that is used in medical settings to evaluate and come to a diagnostic conclusion of the body. This process involves the use of both strong magnetic fields and radio waves in order to produce the image needed to assess the person’s well being. The MRI scan has proven to be effective in examining different parts of the body‚ and the following are examples: Brain‚ spinal cord‚ internal organs‚ heart and blood vessels‚ bones. A normal human adult will have up to 60% of water within

electron microscope‚ we attempted to use a magnetic field to control the electron beam. Utilizing a cathode cay tube (CRT)‚ we oriented a magnetic field perpendicular to the axis of the CRT’s electron beam. From previous experience‚ we decided on using Helmholtz coils to produce a reasonably uniform magnetic field. We measured the deflection of an electron‚ (our dependent‚ “response”‚ variable)‚ as a function of the magnitude of the magnetic field‚ ‚ and the electron’s velocity‚ (our independent

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 wire. The magnitude

The computational domain is simply the physical region over which the simulation will be performed. The E and H fields are determined at every point in space within that computational domain. The material of each cell within the computational domain must be specified. Typically‚ the material is either free-space (air)‚ metal‚ or dielectric. Any material can be used

such as iron‚ nickel‚ cobalt‚ and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs when no electric current is passed through the test object‚ but a magnetic field is applied from an outside source. The magnetic lines of force are perpendicular to

Semiconductors: Band Gap of Germanium and the Hall Effect Friday‚ Section 006 TA: Yilikal Ayino John Greavu with Daniel Erickson & Kevin Haar February 14‚ 2014 PreLab With the new understanding of quantum mechanics and solid-state physics in the 1930’s came the development of semiconductors. Semiconductors are materials such as silicon and germanium in which the current density is non-zero‚ unlike an insulator‚ yet still several magnitudes smaller than that of a conductor. There exists a significant
