- Disorder. Each unit cell has its own dipole moment, which, when there is a net polarisation, are described as ordered. At high T, the direction of the dipole moments randomises, giving a disordered material with no net polarisation.
- Phase transitions that can open up new possibilities for dipole moments to form. In this case, there is a jump at 0°C, and at 90°C, where the loop becomes taller.

CoachThe area of the hysteresis loop changes with temperature because the magnetic properties of materials are temperature-dependent. As temperature increases, the alignment of magnetic domains can be affected, leading to changes in magnetic behavior. This can result in a shift in the hysteresis loop, impacting its area.

What is the direction of the induced current in a loop when there is a change in magnetic field direction?
When there is a change in the direction of the magnetic field in a loop, an induced current is generated in the loop in a direction that opposes the change in the magnetic field.
What is the area of a square loop of side length a?
The area of a square loop with side length a is a2, where "a" represents the length of one side of the square.
WHAT IS THE The phenomenon in which magnetism lags behind the magnetizing current?
The phenomenon you are referring to is known as hysteresis. In hysteresis, the magnetic field in a material lags behind changes in the magnetic field strength, creating a loop-shaped relationship between the magnetic field and the magnetic flux density. This lag is due to the alignment of magnetic domains within the material.
What is the induced electromotive force (EMF) in this loop?
The induced electromotive force (EMF) in a loop is the voltage generated when there is a change in magnetic field within the loop.
How does a microwave oven work as a closed loop system?
A microwave oven works as a closed-loop system by constantly monitoring and adjusting the temperature inside the oven using sensors and a control unit. If the temperature deviates from the set value, the control unit adjusts the power output of the microwave generator to maintain the desired temperature. This continuous feedback loop ensures that the food is heated evenly and efficiently.
