Physics · Magnetic Effects of Current
A 1 cm segment of a wire lying along the x-axis carries a current of 0.5 A along the +x direction. A magnetic field B = (0.4 mT) ĵ + (0.6 mT) k̂ is switched on in the region. The force acting on the segment is:
- 1(-4 ĵ + 6 k̂) μN
- 2(6 ĵ + 4 k̂) μN
- 3(2 ĵ + 3 k̂) μN
- 4(-3 ĵ + 2 k̂) μN✓
Correct answer
(-3 ĵ + 2 k̂) μN
