Which relations below regarding magnetic field and electric field lines are true? 1. Magnetic field lines never begin nor end but always loop around on themselves while electric field lines begin at negative charges and end at positive charges. 2. Magnetic field lines never begin nor end but always loop around on themselves while electric field lines begin at positive charges and end at negative charges. 3. Magnetic field lines come out of north poles outside the magnet and into north poles inside the magnet. Magnetic field lines go into south poles outside the magnet and out of south poles inside the magnet. Electric field lines begin at positive charges and end at negative charges. 4.

What can you change about the simulation

For each of the following diagrams, you will be shown the directions for two variables (v B or F) tor a positive charge moving in a uniform magnetic field and asked for the missing one using the right-hand rule. Remember that dots represent a vector pointed out of the screen and x's represent a vector pointed into the screen. a. What is the direction of the Force on this diagram? O A. right OB. left OD. down toward the bottom of the screen OC. up toward the top of the screen OE. out of the screen OF into the screen b. What is the direction of the Force for this diagram? O A. right O B. left OD. down toward the bottom of the screen OC up toward the top of the screen OE. out of the screen OF into the screen What is the direction of the motion for this diagram? C.
