Explanation:
<em>Sir Isaac Newton's third law of motion</em> says that every action has an equal and opposite reaction.
For example, when you fire a gun, the gun exerts a force on bullet. Even the bullet exerts an equal force on the gun, causing it to recoil.
The Earth revolves around the Sun as the Sun attracts it. The reason why Earth doesn't fall into it is because the Earth also attracts the Sun with an equal gravitational force.
 
        
             
        
        
        
A man pulls on a box with 50 N of applied force while another man pushes on the box from the opposite direction with 60 N of applied force. The box will stand still.

The magnetic force on a moving charge, depends on three four things: the magnitude of the charge, the velocity of the charge, the strength of the magnetic field, and the angle between the velocity and the magnetic field.
