Can someone please explain to me why, a changing magnetic field can produce an electric field and a changing electrical field can produce a magnetic field. Also how do magnetic fields originate, what causes them?

A magnetic field is a region in space around a magnet or a moving electric charge where the magnetic force is exerted. It is also known as a vector field because it has both magnitude and direction.
An electrical field is a region in space around an electric charge where the electric force is exerted. Similar to a magnetic field, it is also a vector field with both magnitude and direction.
Magnetic fields and electrical fields are closely related because they are both part of the electromagnetic force, one of the four fundamental forces in nature. Changes in one field can create the other, and they can also interact with each other.
Magnetic fields can be generated by permanent magnets, electromagnets, and moving electric charges. Electrical fields can be generated by electrically charged objects, such as batteries and power lines.
Magnetic fields are used in many everyday devices, such as motors, generators, speakers, and MRI machines. Electrical fields are used in electronics, telecommunications, and power generation and distribution. Both fields are also used in various industrial and manufacturing processes.
