2 cards from this section. Quick, good the night before a test.
Define Lorentz force.
Think about the charge's movement and its interaction with the magnetic field.
What does the right-hand rule help to determine?
Think about how you can visualize the directions of velocity and magnetic field.
What does the Lorentz force depend on?
Think about the equation we discussed.
True or False: The direction of the Lorentz force is parallel to the velocity.
Remember the right-hand rule discussed.
A charged particle enters a magnetic field with a velocity making a 30-degree angle with the field direction. If the magnetic field strength is 0.2 T and the charge is +1 C, calculate the force exerted if the velocity is 5 m/s.
Don’t forget to consider the sine of the angle!
An electron moves in a magnetic field of 0.1 T with a speed of 2 × 10^7 m/s. Calculate the force on the electron, knowing the charge of the electron is -1.6 × 10^-19 C.
Use the absolute value for force magnitude!
