The length of a part being magnetized by passing an electric current from one end to the other affect 1 permeability 2 strength of magnetic field 3 not affect magnetic field?
Permeability
What do you call the force around a magnet?
the area of magnetic force around a magnet is called the magnetic field
What does an eletromagnet do in a motor?
Provide amoving magnetic force field.
What happens to the magnitude of a magnetic field if the electric field that induces it increases the rate at which it changes?
The magnitude of the magnetic field is decreased
Which layer of the earth produces its magnetic field?
The earth's outer core produces the magnetic field.
What correctly describes magnetic field?
The list of choices submitted with the question containsno correct description of magnetic field lines.
What is Magnetic flux density unit?
"Magnetic flux density" is also known as the magnetic field,The SI unit for this is the Tesla, written as T.CommentMagnetic flux density is not "also known as the magnetic field". It describes the intensity of a magnetic field.
What statements describes the result of reversing the current in a current-carrying in a magnetic field?
When the current is reverted, the magnetic field will also be reverted.
What terms best describes the space surrounding a magnet in which the magnetic forces acts.?
Magnetic field
What is a piece of magnetic material that remains its magnetic proporties after it is removed form a magnetic field?
Many materials which are capable of being effected by a magnetic field will retain some of those properties once its no longer in direct contact with the field. One example is iron. It can become magnetized by being introduced to a magnetic field and then continue to remain magnetic once the source field is removed.
What best describes magnetic field lines?
Magnetic fields are produced because of moving electric charges, and visualizing the very complex mathematical relationships that fall under the magnetic field might become much easier if magnetic field lines were used. A higher density of field lines means a stronger magnetic field. Keep in mind that those lines do not actually exist; they are drawn only to visualize the strength of the magnetic field.
What can you conclude about the orientation of the beam relative to the magnetic field when a beam of electrons passes through a magnetic field without being deflected?
That the beam of electrons were parallel with that of the magnetic field lines.
What describes the production of an electric current by moving a loop of wire through a magnetic field or moving a magnet through a wire loop?
moving a loop of wire through a magnetic Field. The rotation of a coil of copper wire trough a magnetic field changes magnetic field as "seen" from the coil inducing an alternating current.
What are the physical significance of Maxwell's equations?
As per my knowledge,Maxwell's equations describes the relations between changing electric and magnetic fields. That means time varying electric field can be produced by time varying magnetic field and time varying magnetic field can be produced by time varying electric field.
Can a electromagnet works without inductance?
Inductance is the result of energy being stored in a magnetic field. You can't have a magnetic field without inductance.
The area around an object that is affected by the magnetism of that object is the?
A Magnetic Force
Region around a magnet in which magnetic force can act?
Magnetic freild
