Abar magnet is placed on a table so that the north pole faces right. which statement describes the magnetic field lines 2 cm above the table?
a. they are pointing down into the table.
b. they are pointing right to left.
c. they are pointing left to right.
d. they are pointing up out of the table.

option (B)

Explanation:

The magnetic field lines moves from North pole of the magnet to the South pole of the magnet outside the magnet and south pole to north pole inside the magnet. Thus, the magnetic field line at a distance of 2 cm is from right to left.

Option (B)

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

c. magnitude and direction
