Label the magnetic dipole diagram: field lines around a magnet.
1: North Pole, 2: South Pole, 3: Magnetic Field Lines (emerging from North, converging at South)
Label the right-hand rule diagram.
1: Thumb (Velocity, v), 2: Fingers (Magnetic Field, B), 3: Palm (Force, F, for positive charge)
How do you determine the direction of magnetic force on a positive charge using the right-hand rule?
1. Point your thumb in the direction of the charge's velocity (v). 2. Point your fingers in the direction of the magnetic field (B). 3. Your palm indicates the direction of the magnetic force (F).
How do you determine the direction of magnetic force on a negative charge using the right-hand rule?
1. Point your thumb in the direction of the charge's velocity (v). 2. Point your fingers in the direction of the magnetic field (B). 3. The opposite direction of your palm indicates the direction of the magnetic force (F).
What is the effect of placing a magnetic dipole in an external magnetic field?
The magnetic dipole experiences a torque and aligns with the external magnetic field.
What happens when a charged particle moves through a magnetic field?
The charged particle experiences a magnetic force perpendicular to both its velocity and the magnetic field.
What is the effect of increasing the velocity of a charged particle moving through a magnetic field?
The magnitude of the magnetic force on the particle increases proportionally.
What is the effect of a current-carrying wire in a magnetic field?
The wire experiences a magnetic force.
What is the cause of magnetic forces?
The movement of charged particles.
