What is displacement current and conduction current and how they are produced ?
Does change in magnetic field produces current ?
what is the name of current produced by magnetic field ?
Does change in electric field produces current , if yes then what is its name ?

Ofcourse the change in magnetic field can produce an electric current. Assume a conductor in a magnetic field. Now if you change this magnetic field there would be an emf induced in this conductor which is called induced emf. And you can find the direction of induced emf by Fleming's right hand rule. This emf would drive a current if you are shorting the both ends of conductor or connecting a load (as current passes only through a closed path😀) This principle is used in a generator.
The induced emf depends on a lot of factors including how you place the conductor, that if it is parallel to the magnetic field, no emf willl be induced and for maximum induced emf the conductor should be perpendicular to the field.

changing electric field in case of capacitor produces a current equal in magnitude to conduction current but named as Displacement current, that's what Maxwell corrected in Ampere's circuital Law.
