### Does a diamagnetic substance exhibit hysteresis loss?

No, diamagnetic materials do not exhibit hysteresis loss because they do not have permanent magnetic moments that can be aligned and re-aligned in response to an external magnetic field. Hysteresis loss occurs in ferromagnetic materials due to the energy dissipated during the reversal of magnetic domains.

### How does Lenz's Law explain power loss in transformers?

It doesn't, really. The power loss in transformers is broken down into copper loss and iron loss. The copper loss comes from the resistance of the windings in the transformer and depends on the load current, while the iron loss in the magnetic core depends on the magnetic flux density and is constant if the supply voltage is constant.

### Why no power loss in pure inductance?

An inductor is a device which stores energy as a magnetic energy.... Ideal inductor have no resistance.....so there is no power loss.... power loss = (I*I)*R

### Power loss in open circuit test?

There is no power loss in open circuit test. Actually there is iron loss also known as magnetic losses. These include hysteresis and eddy-current losses. This can be described as V1^2/Rc Where V1 is the primary voltage and Rc is the resistance of the magnetic core.

### 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.

### What is the purpose of B-H curve?

The purpose of the B-H curve is to quantify the relationship between the magnetic flux density (B) and the magnetic field strength (H) in a material. It helps in understanding the magnetic properties of materials, such as their magnetization behavior and saturation levels, which is essential for designing magnetic devices and systems.

### Is a magnetic disc affected by a theft detection device or magnetic theft alarm sensor?

Yes, a magnetic disc like a hard drive or floppy disk can be affected by a theft detection device or magnetic theft alarm sensor due to the strong magnetic fields they emit. This can potentially cause data loss or corruption on the magnetic disc. It is best to keep such devices away from magnetic fields.

### Which tool could potentially cause data loss on hard disk or floppy drives?

a magnetic screwdriver

### What is eddy current loss in transformers?

Eddy current loss in Transformers is because of the eddy currents formed in the body of the magnetic core.Whenever a conductor(iron core) exposed to a changing magnetic field a magnetc field produced in the body of the magnetic core.That induce a circulating current in it.Which is called eddy current.In the case transformer it is loss.But it is useful in other purposes.

### Why is the magnetic core laminaled?

The iron core of transformers is laminated to reduce eddy currents, which cause a loss of energy.

### What factors that cause permanent magnet not to generate?

Break in the circuit or loss of magnetic strength of the magnet can result in to no generation

### What is magnetic keeper?

A magnetic keeper, also known as a magnetic shunt or magnetic loop, is a piece of ferromagnetic material that is used to enhance and maintain the strength of a magnetic field. It is typically placed across the poles of a permanent magnet or an electromagnet to prevent the loss of magnetic strength when it is not in use or being used for a specific purpose. The magnetic keeper helps to redirect and concentrate the magnetic flux within the magnet, prolonging its effectiveness.
