the area of magnetic force around a magnet is called the magnetic field
Provide amoving magnetic force field.
The magnitude of the magnetic field is decreased
The earth's outer core produces the magnetic field.
The list of choices submitted with the question containsno correct description of magnetic field lines.
"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.
When the current is reverted, the magnetic field will also be reverted.
The space surrounding a magnet in which the magnetic force acts is called a magnetic field. The magnetic field is the region where magnetic forces are generated and can influence other magnetic materials or moving charges.
The magnetic force exerted in the region around a magnet is called a magnetic field. It is a vector field that describes the magnetic influence of the magnet on other objects or moving charges.
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.
magnetic field is a imaginary area around a manetic material where other magnetic subestences experience some force but flux is the imaginary lines of force that arise from magnet which indicate direction of force around it.
If a beam of electrons passes through a magnetic field without being deflected, then the orientation of the beam is perpendicular to the magnetic field lines. This is because the force acting on a charged particle in a magnetic field is always perpendicular to both the magnetic field and the velocity of the particle, causing the electrons to move in a circular path perpendicular to the 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.
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.
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.
