The differences between the geomagnetism and electromagnetism are given below.
<h3><u>Explanation</u>:</h3>
Geomagnetism is defined as the magnetic field that is located all around the earth. Whereas electromagnetism is defined as the magnetic field that is produced due to passing of electricity through a conductor.
The geomagnetism is formed because of the molten elements of iron etc which are present inside Earth's core, and are continuously moving. It mostly resembles the solid block magnet in its field characteristics. But electromagnetism is different. It can be changed according to the current input which isn't possible for Earth’s magnetic field.
