Compare and contrast the Right-Hand Rule (RHR) and Right-Hand Curl Rule (RHCR).
RHR: Thumb = velocity, fingers = B field, palm = force (on moving charge). RHCR: Thumb = current, fingers = B field (around a wire).
Describe the steps to determine the direction of magnetic force on a moving positive charge.
- Point thumb in the direction of the positive charge's velocity. 2. Point fingers in the direction of the magnetic field. 3. Palm indicates the direction of the magnetic force.
How do you determine the direction of the magnetic field around a current-carrying wire?
Use the Right-Hand Curl Rule (RHCR): Point thumb in the direction of the current; fingers curl in the direction of the magnetic field.
Label the poles and field lines of a bar magnet.
Field lines emerge from the North pole and enter the South pole.
Label the diagram of magnetic domains under an external field.
Individual magnetic domains align under an external field, magnetizing the material.
