Answer:

a) Magnetic field :-The magnetic field B is defined in terms of force on moving charge in the Lorentz force law. ... The SI unit for magnetic field is the Tesla, which can be seen from the magnetic part of the Lorentz force law Fmagnetic = qvB to be composed of (Newton x second)/(Coulomb x meter).

b) Magnetic flux :- In electromagnetism, a sub-discipline of physics, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field (B) passing through that surface. It is denoted by Φ or ΦB. The CGS unit is the Maxwell and SI unit of magnetic flux is the Weber (Wb).

c) Megnatic flux density:- Magnetic Flux Density is amount of magnetic flux through unit area taken perpendicular to direction of magnetic flux. Flux Density (B) is related to Magnetic Field (H) by B=μH. It is measured in Webers per square meter equivalent to Teslas [T].

d) Magnetic motive force:- In magnetic circuit. The magnetomotive force, mmf, is analogous to the electromotive force and may be considered the factor that sets up the flux. The mmf is equivalent to a number of turns of wire carrying an electric current and has units of ampere-turns. If either the current through…

Explanation:

The magnetic field B is defined in terms of force on moving charge in the Lorentz force law. ... The SI unit for magnetic field is the Tesla, which can be seen from the magnetic part of the Lorentz force law Fmagnetic = qvB to be composed of (Newton x second)/(Coulomb x meter).

magnetic flux. ... The total number of magnetic lines of force crossing any surface in the magnetic field is termed as magnetic flux. ∴ Φ = BA cos θ SI unit of magnetic flux is weber.

The magnetic flux density or magnetic induction is the number of lines of force passing through a unit area of material, B. The unit of magnetic induction is the tesla (T).

Magnetomotive force, also known as magnetic potential, is the property of certain substances or phenomena that gives rise to magnetic field s. Magnetomotive force is analogous to electromotive force or voltage in electricity.
