3 cards from this section. Quick, good the night before a test.
What is the formula to calculate the force on a charged particle in a magnetic field?
Remember the key variables in the equation.
What happens to the magnetic force if the charge moves perpendicular to the magnetic field?
Think about the role of sine in the force equation.
What is the role of theta in the magnetic force formula F = qvBsin(θ)?
Consider which angle gives the strongest interaction.
True or False: A charged particle in a magnetic field always moves in a straight line.
Think about the forces acting on the charged particle.
An ion with charge +3 e (where e = 1.6 x 10^-19 C) and mass 6.65 x 10^-27 kg enters a magnetic field of 0.5 T with a speed of 1 x 10^4 m/s. Determine the radius of its path.
Pay attention to the charge magnitude: +3e.
Explain how changing the velocity of a charged particle affects its path in a magnetic field and provide an example.
Think about the impact of speed on circular motion.
