How ferroelectrics are different from ordinary dielectrics?
ferroelectrics have strong magnetic field and also magnetic susceptibility & permeability value are strong (>1) but dielectric have feebly magnetic field & it have lesser value. ...
Asked in Physics
How will the magnetic field produced by an electromagnet change if the iron core were replaced by an aluminum core?
The magnetic field will be not be as strong. It will be weaker.
Asked in Earth Sciences, Magnetism
What is the layer in which the magnetic field of the Earth is produced?
The outer liquid core produces the strong magnetic field of the Earth, through the dynamo effect. ...
How does the magnetic field in a loudspeaker work?
Speakers have very strong magnets, hence, strong magnetic fields. That's how they work, by magnetically induced vibration that creates sound. ANSWER they do have magnetic field but they works because the ac in the coils will cause displacement ...
Where is the magnetic field on a magnet the stongest?
The magnetic field of a magnet is strongest right at the poles, both the north pole and the south pole (which are equally strong). ...
How do you turn non-magnetic materials into magnetic materials?
Putting a magnet-friendly substance such as iron in a strong magnetic field can magnetize it. The individual iron particles can align with the magnetic field and together form a magnet. ...
Asked in Science
What can you infer about the strength of a magnetic field based upon the position of the iron filings?
The profile of the iron filings reflects that of the magnetic field. When the magnetic field is strong, the lines will be really tight (small separation) and thick (height and width). ========================= ...
