Magnetic Force and Right-Hand Rule

The video tutorial explains magnetic fields and how to determine the direction of force on wires and subatomic particles using the right-hand rule. It covers the use of a horseshoe magnet, the concept of conventional current, and the equations for calculating magnetic force. The tutorial also discusses the behavior of subatomic particles in magnetic fields and introduces the left-hand rule for negative particles.
