Question

Problem 5 (Total: 6 pts) An electron is moving as shown in the diagram below (x to the right, y up, z out of page) At the location A what is the direction of the magnetic field made by the electron? Cirele the letter of your choice: +x x +yy+z -z zero At the location B what is the direction of the magnetic field made by the electron? Circle the letter of your choice: +x x tyy +z 2 zero At the location C what is the direction of the magnetic field made by the electron? Circle the letter of your choice: +x x ty y+z z zero

Explanation / Answer

Solution:

At location A: The the point 'A' is axial point of the motion of the electron. There will not be magnetic field. Therefore the answer is Zero.

At location B: If you apply right hand thumb rule, the direction of magnetic field at point 'B' is into the page. Therefore, the answere is -Z

At location C: If you apply right hand thumb rule, the direction of magnetic field at point 'C' is out of the page. Therefore, the answere is +Z
