As we apply a magnetizing field (H- A/m) then the substance would get magnetic induction (B- unit tesla). As we increase the value of H, B also increases in the same direction in case of ferro magnetic material. But B attains a max value. Then as we start decreasing H back to zero, B does not fall to zero. But some residual B is found in the material. This is called retentivity. Now so as to make B to zero then we have apply H in the negative direction. So as we complete on oscillation of H, B also changes but it goes along a curved path.
Hence the lagging of B with H is known to be hysteresis
What else can I help you with?
Why the hysteresis curve is so fat in a sample?
The fatness of a hysteresis curve in a sample can be due to factors like impurities in the material, sample geometry, and microstructural features causing domain movement with different energy barriers. These factors can lead to a wider range of magnetic responses within the sample, resulting in a broader hysteresis curve.
How do you calculate the Hysteresis loss given a B-H curve?
hysteresis loss= K B^1.6 egs/sec where k is STEINMEITZ coefficient and B is the maximum magnetic flux density
Explain the B-H curve?
The B-H curve, also known as the magnetization curve, represents the relationship between the magnetic field (H) applied to a material and the magnetic induction (B) it exhibits in response. It shows how magnetization changes with the strength of an external magnetic field and helps characterize the magnetic properties of a material, such as ferromagnetic materials showing hysteresis.
What is magnetic hysteresis?
Magnetic hysteresis is the phenomenon where the magnetization of a material depends not only on the current magnetic field, but also its history. When the magnetic field is applied and then removed, the material retains some magnetization, showing a lag or "memory" in its response to changing magnetic fields. This results in the characteristic hysteresis loop observed in magnetic materials.
Is hysteresis desirable in a transducer why?
Not usually. In most applications you want a linear response in voltage to stimulus with as low a time constant for change as possible. This is the ideal and not completely achievable or justified by the cost. As a rule the smaller the stimulus being measured the less desirable hysteresis. Think of an elephant sitting on the scale it takes some moments for the springs and counter weights to reach an equilibrium. A funny thing though. In biology most sensory receptors show some type of hysteresis. That may be because they respond with a frequency encoded response though.
Describe how to distinguish a paramagnet from a ferromagnet by m versus h curves?
A ferromagnet has a steep gradient B /H curve with very noticeable hysteresis. A paramagnet has a shallow curve with almost no hysteresis.
Why the hysteresis curve is so fat in a sample?
The fatness of a hysteresis curve in a sample can be due to factors like impurities in the material, sample geometry, and microstructural features causing domain movement with different energy barriers. These factors can lead to a wider range of magnetic responses within the sample, resulting in a broader hysteresis curve.
How do you draw hysteresis curve using excel graph?
To draw a hysteresis curve in an Excel document you need to choose chart under the Insert tab, specifying a scatter chart. Then you will specify your data, which should be listed in columns in an Excel document. You can add the trend curve by selecting the Chart tab and going through the options offered.

What is the formula of energy loss in hysteresis curve?
P/Vol=A/T P: Power Vol: Volume A: Area T: Period
Can you measure hysteresis loss for diamagnetic materials?
what is hysteresis losses
What is Hysteresis motor working principle?
It is a special type of synchronous motor.It works on the principle of hysteresis and the torque is produced due to hysteresis
Diagram of hysteresis motor?
can Hysteresis motor use like alternator
What is hysteresis in economics?
It is a situation in business cycle where the long run equilibrium depends on the path followed in short run. For example, shift in labor supply curve in short run due to economic shocks causes wages to rise. Even after the economy stabilises the tendency of wages not to fall is described as hysteresis.(rchekurir@yahoo.co.in)
How do you calculate hysteresis?
max hysteresis = max(O_decreasing - O_increasing) / (O_max - O_min)
How can hysteresis loss in magnetic material may be reduced?
Hysteresis losses depend on the type of metal used to manufacture the magnetic circuit of a machine. Most magnetic circuits are made from silicon steel. Generally speaking, there's not much you can do to reduce hysteresis losses as that has already been factored in by the machine's designer.
