List of top Physics Questions on Magnetic Force asked in MHT CET

Lorentz magnetic force is acting on a particle of charge q moving with velocity $\vec{V}$ in a magnetic field $\vec{B}$. The work done by this force on the charged particle is}
A long straight wire carries a current of 10 A. A proton moves parallel to the wire at a distance of 0.05 m with a velocity of \( 2 \times 10^5 \, \text{m/s} \) in the same direction as the current. Find the magnitude of the magnetic force acting on the proton. (Given: Charge of proton \( q = 1.6 \times 10^{-19} \, \text{C} \), permeability of free space \( \mu_0 = 4\pi \times 10^{-7} \, \text{Tm/A} \)).
