To find the magnetic force acting on an alpha particle moving in a magnetic field, we can use the formula for the magnetic force: \[ \mathbf{F} = q (\mathbf{v} \times \mathbf{B}) \] Where: - \( \mathbf{F} \) is the magnetic force, - \( q \) is the charge of the particle, - \( \mathbf{v} \) is the velocity of the particle, ...
