Question

S F Care Battery Figure 5 A compass inside a coil connected to a battery Do not connect the coil to the battery at this time. The lab instructors do not take points off for wrong answers to the questions in Activity #6. Please watch this video first... 6.1 Carefully inspect your coil to determine which way the wire in the coil is wound. If you ar not sure, ask your lab instructor to assist you. 0 13 For someone looking at your coil face-on, like Figure 5, and if the battery were connected as in Figure 5, would the current flow clockwise or counterclockwise? I'll give you this answer... The current flows counterclockwise. 214 If your coil were connected to the battery as in Figure 5, which way would the magneti field inside the coil point (for a person looking at the coil face-on)? Out of the paper and

Answer 1

14) We will use right hand thumb rule to get the direction of the magnetic field.Since the current flows counter-clockwise, so for a person looking at the coil face on, the magnetic field will be out of the paper and towards the person.

15) A compass is an extremely simple device. A magnetic compass (as opposed to a gyroscopic compass) consists of a small, lightweight magnet balanced on a nearly frictionless pivot point. The magnet is generally called a needle. The Compass's north would point in the direction of field lines since field lines.

Since the magnetic field lines inside the coild is out of the plane of paper, hence, when a compass is placed inside , it will align itself with the magnetic field and would point out of the paper towards you.

16) When the compass is placed out of the coil and on top of it, the magnetic field there is into the plane of paper. Again, the compass will align itself in the direction of magnetic field and would point into the paper away from you.
