🔬 MCAT Exam Prep

A wire carrying current in a magnetic field experiences a force described by:

A Coulomb law
B F = qvBsinθ (Lorentz force on moving charges)
C Ohm law
D Faraday law

✓ Correct Answer: Option B

The force on a current-carrying wire in a magnetic field comes from the Lorentz force on moving charges: F = ILBsinθ, derived from F = qvBsinθ.

💡 Why is B) the correct answer?

The correct answer to the question "A wire carrying current in a magnetic field experiences a force described by:" is Option B: F = qvBsinθ (Lorentz force on moving charges).

The other options — A) Coulomb law, C) Ohm law, D) Faraday law — are incorrect for this MCAT Exam Prep question. As explained above: The force on a current-carrying wire in a magnetic field comes from the Lorentz force on moving charges: F = ILBsinθ, derived from F = qvBsinθ.
