## What is the formula for hysteresis?

The hysteresis loss per second is given by the equation[20]: Hysteresis loss, Ph= (Bmax)1.6f V joules per second (or) watts. Where, f: supply frequency in Hz, V: volume of core in cubic meters, η‟: hysteresis coefficient, Bmax: peak value of flux density in the core.

## What is a magnetization curve and what is the hysteresis loop?

A curve, or loop, plotted on B-H coordinates showing how the magnetization of a ferromagnetic material varies when subjected to a periodically reversing magnetic field, is known as Hysteresis Loop.

**What is a magnetisation curve?**

Definition of magnetization curve : a graph representing changes in the condition of a magnetizable substance with magnetizing force H as abscissa and either magnetization I or induction B as ordinate.

### How is hysteresis calculated in instrumentation?

How to Calculate Hysteresis

- Create a table.
- Enter your upscale results.
- Enter your downscale results.
- Subtract the upscale result (yupscale) by the downscale result (ydownscale).
- Find the absolute value of the result in step 4.
- Repeat Steps 4 and 5 for each measurement with results both upscale and downscale.

### How do you calculate H from BH curve?

The relationship between B and H is B=μH. So if you have a B-H curve for a given material, you can find your permeability, μ, by finding B divided by H. Keep in mind that permeability is a function of H, it is not constant for all values of H.

**What is hysteresis value?**

Hysteresis is defined as the deviation of the contact angle from its theoretical (and mean) value due to physical phenomena like microscopic surface defects and roughness.

#### What is BH curve and hysteresis loop?

A hysteresis loop (also known as a hysteresis curve) is a four-quadrant graph that shows the relationship between the induced magnetic flux density B and the magnetizing force H. It is often referred to as the B-H loop. From hysteresis loops, we can determine a number of magnetic properties about a material.
