Electron Determine the magnetic field direction that causes the negatively charged particle shown in the figure to experience the indicated magnetic forces.

Magnetic resonance imaging (MRI) is one of the most useful and rapidly growing medical imaging tools. It non-invasively produces two-dimensional and three-dimensional images of the body that provide important medical information with none of the hazards of x-rays. MRI is based on an effect called nuclear magnetic resonance (NMR) in which an externally applied magnetic field interacts with the magnetic fields of nuclei of certain atoms, particularly those of hydrogen (protons). The external magnetic field is created by a large coil. This field interacts with the hydrogen atoms in the patient's body to form images. a) To see why an MRI utilizes iron to increase the magnetic field created by a coil, calculate the current needed in a 420-loop-per-meter circular coil 0.66 m in radius to create a 1.3 T field (typical of an MRI instrument) at its center with no iron present. /= A Introducing ferromagnetic materials inside coils greatly increases the magntic field inside the coil for a small…

QUESTION 1 A particle with a charge of 5.60 is traveling with a velocity of 3000 m/x in the direction when it enfers a region of space with an electric field and a magnetic held. The electric field has a magnitude of 240 N/C and points in a direction that is 25 above the +x-axis, the magnetic field has a magnitude of +1.87 and points out of the page See the attached figure Find the magnitude of the net force acting on this particle when it enters this region of space This is part 1 of 2 for this problem 1 Bo 100 tw QUESTION 2 For the particle in problem 1. find the direction of the net force acting on the particle when it enters the region of space. Your answer needs to be the angle measured from the +y-axis. This is part 2 of 2 for this problem
