PRACTICE / Magnetic force on a wire
Force on a current segment
A straight 0.20 m wire segment carries 3 A perpendicular to a uniform 0.40 T magnetic field.
Find its magnetic-force magnitude.
Organize the givens & assumptions
- L = 0.20 m
- I = 3 A
- B = 0.40 T
- θ = 90°
Straight current-carrying segment in a prescribed uniform external field; current perpendicular to field.
- A
- B
- C
- D
