Answer:

The movement of atoms changes the phase from the cubic phase to the tetragonal, resulting in the production of a dipole moment along the [100] direction. The switching to a cubic structure is the reason for the polarisation spontaneously disappearing above 120°C.

hii friend this is your answer

Explanation:

This view shows the cubic nature of Barium Titanate. The movement of atoms changes the phase from the cubic phase to the tetragonal, resulting in the production of a dipole moment along the [100] direction. ... The switching to a cubic structure is the reason for the polarisation spontaneously disappearing above 120°C.

How does a solenoid behave like a magnet? Can you determine the North and South poles of a current carrying solenoid using a bar magnet? Explain.

ans1) A solenoid behaves like a bar magnet when a current is passed through it. ... Yes, the north and south poles of a current–carrying solenoid can be determined with the help of a bar magnet. We can bring the North of a Bar Magnet towards one end of the solenoid. If the magnet is repelled, the end is north end of the solenoid ..
