What are the key differences between the Right-Hand Rule (RHR) and the Right-Hand Curl Rule (RHCR)?
RHR: Used to find the force on a charge or wire in a magnetic field. | RHCR: Used to find the direction of the magnetic field created by a current-carrying wire.
Compare the forces between parallel and anti-parallel current-carrying wires.
Parallel Currents: Wires attract each other. | Anti-Parallel Currents: Wires repel each other.
Define magnetic force vector
The force exerted on a current-carrying wire or moving charge due to a magnetic field.
Define current in the context of magnetic forces on wires.
The rate of flow of electric charge through a wire, measured in Amperes (A).
Define length vector of a wire in a magnetic field.
A vector representing the length of the wire segment within the magnetic field; its direction is the same as the current.
Define magnetic field vector .
A vector field that describes the magnetic influence of electric currents and magnetic materials.
Define torque on a current loop.
A rotational force that causes a current loop to rotate in a magnetic field.
Define permeability of free space .
A physical constant that relates the magnetic field to the electric current that produces it; .
In the image of the wire loop in a magnetic field, label the current direction, magnetic field direction, and the direction of the resulting force on each segment of the loop.
1: Current direction, 2: Magnetic field direction, 3: Force direction.
Label the diagram illustrating the Right-Hand Rule for force on a wire in a magnetic field.
