In a magnetization cycle, a large hysteresis loop indicates ____.
Answer the material is nonmagnetic
a large amount of energy loss due to heating
the size of the material is large
the material will not remain well magnetized
A large hysteresis loop in a magnetization cycle indicates that the material will not remain well magnetized.
To understand this, let's break down the key concept: hysteresis loop. In a magnetization cycle, a hysteresis loop shows the relationship between the applied magnetic field and the resulting magnetization of a material.
A large hysteresis loop indicates that there is a significant difference between the magnetization of the material when the applied magnetic field is increasing (going up the loop) and when the magnetic field is decreasing (going down the loop). This means that when the applied magnetic field is reduced to zero, the material retains a relatively low level of magnetization.
This is often undesirable because it means that the material does not have a strong magnetic memory. In other words, it doesn't "remember" its magnetization well when the applied magnetic field is removed, which makes it less useful for applications requiring long-term magnetization, such as in permanent magnets.
Therefore, a large hysteresis loop suggests that the material will not remain well magnetized, as it does not retain a strong magnetic field once the external magnetic field is removed.
