Question
Part A
You have a magnet on which the poles are not marked. How can you determine which pole is north and which is south if you have another magnet?
Place __________ on a swivel. Bring the North pole of ___________ close to the swivel and observe the behavior of _______________ . Since opposite poles _____________, the side of the unmarked magnet that turns toward the marked North pole is the ______________ pole.
Words to choose from: attract, repel, the marked magnet, the unmarked magnet, South, North
Part B
You have a magnet on which the poles are not marked. How can you determine which pole is north and which is south if you have a current-carrying coil?
Connect ______________ to a battery and determine the direction of the current in ____________________. Hold the current-carrying coil and place ______________ on the swivel. Use ___________________ rule for the fields to determine the direction of the magnetic field produced by ______________. The tip of the magnetic field arrow inside ___________________ is analogous to the North pole of _______________ in part A. Then repeat the procedure described in part A.
Words to choose from: the right-hand, the left-hand, the marked magnet, the coil, the unmarked magnet
Explanation / Answer
Part A
Same pole repel each other.opposit pole attract.
According to the blank sequence
1 . The unmarked magnet
2 . The marked magnet
3. The unmarked magnet
4. Attract
5. South
Part B
When coil lie on the plane of the paper
When you see current flowing clock wise direction then you see this is the South pole of the coil magnet.
Current flow counterclockwise it will be North Pole.
Blank in sequence
1 the coil
2 the coil
3 the unmarked magnet
4 the right hand rule
5 the coil
6 the coil
7 the marked magnet. Since it should be South pole but
Remember you hold the coil. Other side behave North pole which is in front of the unmarked magnet.
