A magnetic field is the invisible field of magnetic force that is exerted on substances that are sensitive to magnetism. Magnetic fields have been studied by scientists and are used in applications such as compasses and MRI equipment.

### What is a magnetic field will be produced at some point in space if the electric field at the point?

As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.

### 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.
