How does the force change as the distance from the source increases:magnetic 

# data[].attributes.body
Whenever electrons flow through a conductor a magnetic field will develop the field excerts over a certain distance.  As distance increases, magnetic force decreases.

What determines the direction of the field electromagnetic? 

# data[].attributes.body
The right hand rule is a way to visualize the direction of the magnetic field caused by an electric current.   If current is seen as flowing upward, the magnetic field is perpendicular and follows the curled fingers.  Electromagnetic force points out from palm.

The change in gravitational force as distance from the source increases

# data[].attributes.body
Gravitational force decreases as distance from the source increases.

How electromagnetics force changes over distance

# data[].attributes.body
As distance increases, electromagnetic force decreases.

Strength and orientation doesn't change over time which makes the fields range infinite.
