Letusknowwhy Apr 16, What are factors on which the strength of induced current depends? Recommend 3 Comment 0. Amarnathreddy M. Answer: The strength of the induced current directly depends upon the following factors. Strength of the magnetic field Number of the turns in the coil Relative speed between the coil and the magnet.

Adjacent domains will generally not be oriented in identical directions. In magnetized materials, some domains will cancel, but the average domain orientation will be in one direction, producing a net magnetic field. In unmagnetized materials, the domains are randomly oriented and cancel, so no observable field is created.

The figure to the right illustrates these concepts. The concept of magnetism being entirely due to the motion of charges has been modified significantly in the 20th century, thanks to quantum mechanics. The Bohr model of the atom must be modified to include uncertainty. We can never determine exactly the trajectory of an electron or say for certain where it will be found. The uncertainty principle requires that we instead say only where the electron is most likely to be found.

Until we measure the position of the electron, its wave function is spread out over all space, with a higher probability of finding the electron in the classical orbit described by Bohr. Not all are aligned, but. Like an electric field, a magnetic field may be represented with field lines. These lines and the magnetic field point from the north pole of a magnet to the south pole of a magnet , as shown in the figure to the left.. Unlike electric field lines, magnetic field lines are always closed - they never have a starting point or stopping point.

Whenever you have a north pole, you must have a south pole as well. Another way to say this is that magnetic monopoles single poles do not exist. Electric monopoles, on the other hand, exist in abundance. Examples are an electron, a proton, or any other charged particle. Even the magnetic field produced by a current-carrying wire must form complete loops.

Above, you were told that a loop of current-carrying wire produces a magnetic field along the axis of the wire. The right-hand rule gives the direction of the field inside the loop of wire. The magnetic field turns back the other way outside of the loop.

As shown in the figure on the right, this magnetic field from a loop of current-carrying wire looks similar to the field from a permanent bar magnet. To be exact, the symbol B represents magnetic flux density, also called magnetic induction, not magnetic field. The true magnetic field is denoted by H. H and B differ only by a material-dependent constant. For most purposes, the difference is inconsequential, so we will refer to B as the magnetic field.
