All Flashcards
What is the effect of a magnetic force on a moving charged particle?
The magnetic force causes the particle to curve, often resulting in uniform circular motion if the field is uniform and the velocity is perpendicular to the field.
What causes the aurora borealis?
Charged particles from the sun interacting with Earth's magnetic field.
What happens when a charged particle moves perpendicular to a uniform magnetic field?
The particle undergoes uniform circular motion.
What is the result of balancing electric and magnetic forces on a charged particle?
Particles with a specific velocity can be selected (velocity selector).
What do the magnetic field lines look like around a bar magnet?
Magnetic field lines emerge from the north pole and enter the south pole of the magnet.
What are the steps to determine the direction of magnetic force using the Right-Hand Rule (RHR)?
- Point thumb in the direction of the positive charge's velocity. 2. Point fingers in the direction of the magnetic field. 3. Palm shows the direction of the force.
What are the conditions for a charged particle to experience a magnetic force?
- The object must be charged (q ≠ 0). 2. The particle must be moving (v ≠ 0). 3. There must be a magnetic field present (B ≠ 0). 4. The particle's velocity and the magnetic field must have a perpendicular component.
