3 cards from this section. Quick, good the night before a test.
What does the Lorentz force refer to?
Think about what happens to a wire in a magnetic field.
What is the formula for calculating the force on a current-carrying conductor?
It combines magnetic field strength, current, length and angle.
What is the Lorentz force?
Focus on the relationship between current and magnetic fields.
The angle θ in the formula F = BIL sin θ is important because:
Consider what happens if the angle is zero.
A current-carrying wire 10cm long with a current of 12 A is placed perpendicularly in a magnetic field of 6 T. Determine the force on the wire.
Keep in mind the unit conversion for length!
An airplane wing generates lift using the Lorentz force principle when current-carrying wires are placed within a magnetic field. Describe how the angle affects lift generation.
Visualize how the lift shifts as the wire's angle adjusts!
