Feb 02, 2018 · Electric Field Mapping Equipment: mapping board, U-probe, 5 resistive boards, templates, knob adjustable DC volt-meter, 4 long leads, 16 V DC for wall strip, 8 1/2" X 11" sheets of paper Reading: Topics of electric elds. Precautions 1.Before turning mapping board over, remove voltage leads from board. The magnetic field is an exerted area around the magnetic force. It is obtained by moving electric charges. The direction of the magnetic field is indicated by lines. While the electric fields are generated around the particles which obtain electric charge. During this process, positive charges are drawn, while negative charges are repelled.
Pre-lab questions for the “Electric Field and Electric Potential” lab. 1) What is the electric field inside an empty uniformly charged sphere? Hint: recall Gauss’ Law. 2) Now let’s consider a uniformly charged ring, as shown in Fig 1. Using symmetry arguments, what could be the direction of the electric field (if applicable) at an arbitrary
