Polina Pomerants Partners: Hue, Jane Physics 2022 Enpeng Du Lab #28 07/08/09 Mapping the Electrostatic Potential & Electric Field Purpose: The objective of this lab is to visualize some electrostatic potentials and electric fields of various charge configuarations. Specifically, the goal is to observe a relationship between electric currents and magnetic fields; that is, to show that the electric current produces the magnetic field. Magnetic fields are produced by charges moving relative to a frame of reference and thus describe forces between moving charges. We will use the conducting paper to map equipotentials and electric fields. Theory: The relationship between electric and magnetic fields, shown as E and B, can demonstrated by this equation: F= q (E+v *B) This is Lorentz force law. Procedure: Part 1 1. Mount the conductive paper. 2. Connect the electrodes to a DC power. 3. Connect the wire terminals with electrodes and other wire terminals with the power supply.

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
