Electromagnetics-Introduction

1. ELECTROMAGNETICS:

Electromagnetic is a branch of physics which deals with effect of both electrical and magnetic fields. Field is defined as the space or region around the charge body. 

2. MAGNETIC FIELD:

If the field is due to magnetic effect is called magnetic field

3. ELECTROMAGNETIC FIELD:

Moving charge produces a current and current carrying conductor produces a magnetic field in such case electric and magnetic fields are related to each other. such fields are called electromagnetic field.
