What is one way that an electric field is different from a magnetic field?

Answer with Explanation:

Electric field:It is the force per unit charge experienced by rest charge at any given point.

It is the area around the charge which is placed at rest.It is represented by E.

Mathematical formula:

Magnetic field:It is an area around moving charge in which moving charge particle experienced  magnetic force in that area.

Magnetic field is represented by B.

Mathematical formula :

Where B=Magnetic field

q=Charge on particle

v=Velocity of particle

F=Magnetic force exert on particle

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
