Answer:

1. A magnetic charge creates a magnetic field.

Magnetic fields are produced by all moving charged particles. This means any stationary charge or any neutral object does not produce a magnetic field.  

2. A changing magnetic field causes a changing electric field.

A changing electric field creates a magnetic field and a changing magnetic field creates an electric field.  

3. The successive production of electric and magnetic fields results to the creation of electromagnetic (EM) wave.

Electromagnetic waves are the created through the combination of electric and magnetic fields which are produced by moving charges.

4. An EM wave propagates outwards from the source.

An electromagnetic wave radiates outwards from a source at the speed of light. This means that the oscillating electric and magnetic fields created from the source travel away from it. The electric and magnetic fields travel in a direction perpendicular to each other.  

5. Electromagnetic waves do not need a medium to transfer energy.

Electromagnetic waves do not require a medium to travel or propagate. This means they can travel not only through matter but also through a vacuum or empty space. It doesn’t lose energy as it travels.
