Chapter 21 WebLab#2 “Charge in a Magnetic Field” Part One * Go to the following website: http://www.surendranath.org/Applets.html * Move your cursor to the upper left corner of the screen, where it says “Applet Menu”. Move your cursor down to where it says “Electricity”. Click on “Charge in a Magnetic Field”. Click on the black rectangle to open the simulation. * Observe the motion of the (positive) charge in the magnetic field. Note the direction of the force on the charge. * Change the strength of the magnetic field and observe the motion. * Change the mass of the particle and observe the motion. * Change the velocity of the particle and observe the motion. Part Two * Go to the following website: http://www.mhhe.com/physsci/physical/giambattista/magnetic/magnetic_field.html * Click on the “Fire!” button to launch the charged particle in the magnetic field. Click and drag on the screen to rotate your view. * Change the strength of the magnetic field and observe the motion.

Unformatted text preview: * Change the mass of the particle and observe the motion. * Change the velocity of the particle and observe the motion. * Change the charge of the particle and observe the motion. * Change the initial direction of the particle and observe the motion. Questions: 1) Describe the general motion of a charged particle in a magnetic field. 2) How does increasing the strength of the magnetic field alter the motion of the particle? 3) How does increasing the mass of the particle alter its motion? 4) How does increasing the velocity of the particle alter its motion? 5) How does increasing the magnitude of the charge of the particle alter its motion? 6) How does changing the sign of the charge of the particle alter its motion? 7) How does changing the initial direction of motion of the particle alter its subsequent motion? 8) How is the radius of a particle’s motion related to the net force acting on the particle?...
