Explain -TESLA and compare it with TESLA?

Solution

Tesla is a unit of measurement of the strength of a magnetic field. It is a derived unit of the International System of Units, the modern form of the metric system.The strongest fields encountered from permanent magnets are from Halbach spheres which can be over 4.5 T. The strongest field trapped in a laboratory superconductor as of July 2014 is 17.6 T. The record magnetic field has been produced by scientists at the Los Alamos National Laboratory campus of the National High Magnetic Field Laboratory, the world\'s first 100-tesla, non-destructive magnetic field

In the production of the Lorentz force, the difference between these fields is that a force from a magnetic field on a charged particle is generally due to the charged particle\'s movement, while the force imparted by an electric field on a charged particle is not due to the charged particle\'s movement. This may be appreciated by looking at the units for each. The unit of electric field in the MKS system of units is newtons per coulomb, N/C, while the magnetic field (in teslas) can be written as N/(C·m/s). The dividing factor between the two types of field is metres/second (m/s), which is velocity. This relationship immediately highlights the fact that whether a static electromagnetic field is seen as purely magnetic, or purely electric, or some combination of these, is dependent upon one\'s reference frame (that is: one\'s velocity relative to the field).

In ferromagnets, the movement creating the magnetic field is the electron spin (and to a lesser extent electron orbital angular momentum). In a current-carrying wire (electromagnets) the movement is due to electrons moving through the wire (whether the wire is straight or circular).
