Dear Experts,
May I know the difference between electric charge and charge of magnetic field?

An electric charge is ideally an electron. A magnetic field is what is created when the charge is 'moved'. If you need to know the charge of a magnetic field, you need derive from B-Field to charges/sec. In our world this is typically done via a conductor (typically metal but it can be a gas too).

Basically region around a magnet or a current carrying conductor is said to be magnetic field.
ulltimately whatever is causing magnetic field is nothing but charge again.
Its known that region around a charge is electric field , so the big question is how is magnetic field different from electric field?
How does it originate?
Why doesnt magnetic field effect a charge at rest?

Although not easy to understand Maxwell equations (gauss law) define the relation between electric field and electric charges. They also define that there is no such a thing as a magnetic charge.
That is: an electric charge exists but a magnetic charge does not exist. There is a magnetic dipole but it is not the equivalent of a charge for the magnetic field.
Other maxwell equations (ampere law) describe the static magnetic field produced by a moving charge. Current implies charges in movement so it generates magnetic field.
Maxwell correction to ampere law describes that a changing electric field generates a magnetic field thus predicting the existence of electromagnetic waves. An accelerated charge generates an electromagnetic wave.
Still another maxwell equation (faraday law) describes that a current is generated by a varying magnetic field. Generators/alternators works thanks to this.
