4.3 Moving Charges in Magnetic Fields Flashcards
1
Q
Lorentz force
A
The force that is exerted by a magnetic field on a moving electric charge.
2
Q
When you want to determine the direction a charged particle will be forced when moving through a magnetic field.
A
Point your fingers in the direction of the magnetic field, your thumb in the direction of the electron flow, and your palm will point in the direction of the magnetic force.
3
Q
Why is there a magnetic force?
A
Because of the interaction between the magnetic fields. It generates the fields.
