- IV is the one I need help withWhich 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. Magnetic field lines begin at north poles and end at south poles while electric field lines loop around on themselves. 5. Magnetic field lines begin at south poles and end at north poles while electric field lines loop around on themselves. 1 and 4 2 and 5 2 and 4 1 and 3 1 and 5 2 and 3Two long wires carry 10 A currents in the directions shown in the figure (Figure 1).

- Q7. If you were to move the north pole of a bar magnet into the front of your coil, what is the direction of the induced current when viewed from the front? To reach your conclusion, answer each of the following (see next page): Motion of the magnet as viewed from above. The arrows by the magnet indicate the direction in which the magnet moves, not necessarily the direction of B. a) Is the flux within the coil increasing, decreasing, or remaining constant? Explain in the space below. b) Viewing the coil “from the front", what is the direction of Bo within the coil? Done as an example to clarify perspective. "From the front" means looking into the coil. (X) (since B lines point away from "N") c) Viewing the coil “from the front", what is the direction Bind within the coil? d) What is the direction of Iind in the coil, when viewed from the front? e) Which way will the needle deflect?16. A small, circular loop of conducting wire is near a long, straight wire that carries a steady electric current I to the right, as shown above. Which of the following actions will result in a clockwise induced electric current in the wire loop? I. The wire loop is pulled vertically upward in the plane of the page (away from the wire) at a constant speed. II. The current in the straight wire is steadily increasing. III. The wire loop is rotated about a diameter through a small angle so that it is no longer in the plane of the page.

(B) What is the basic difference between this Law (question A) and Faraday’s Law of Induction? (C) If a static magnetic field can’t produce a current than in which situation, we use Lenz’s law to define the current direction. Explain with example.
