Magnetic Force A force experienced by a moving charge in a magnetic field, always perpendicular to the velocity. Right-Hand Rule A method to determine the direction of magnetic force on a positive charge moving in a magnetic field. Centripetal Force The inward force required for an object to move in a circular path, provided by magnetic force in this context. Centripetal Acceleration Acceleration directed towards the center of a circular path, calculated as v squared over r. Radius The distance from the center to the edge of the circular path of a charge in a magnetic field. Momentum The product of mass and velocity, represented as mv, crucial in deriving the radius equation. Helical Motion The spiral path of a charge moving at an angle to a magnetic field, combining circular and linear motion. Uniform Field A magnetic field with constant magnitude and direction, affecting the motion of charges uniformly. Tesla The unit of magnetic field strength, symbolized as T, used in calculating the force on a charge. Sine of Theta A trigonometric function used in calculating magnetic force, with theta as the angle between velocity and field. Circular Arc A segment of a circle's circumference, used to describe the path of a charge in a magnetic field. Displacement The change in position of a charge, tangential to the circular path in a magnetic field. Coulomb The unit of electric charge, symbolized as C, used to quantify the charge of particles like electrons. Velocity The speed and direction of a moving charge, crucial in determining the radius of its circular path. Speed of Light The maximum speed limit in the universe, used as a reference to check the reasonableness of calculated velocities.
