Introduction

The magnetic force on a moving charge is a fundamental concept in physics, governed by the Lorentz force equation. This equation describes the force experienced by a charge moving through a magnetic field. In this article, we will explore the magnetic force on a proton moving at a specific velocity through a magnetic field of a given strength.

The Lorentz Force Equation

The Lorentz force equation is a fundamental concept in physics that describes the force experienced by a charge moving through a magnetic field. The equation is given by:

F=q(E+v×B){ \mathbf{F} = q(\mathbf{E} + \mathbf{v} \times \mathbf{B}) }

where F\mathbf{F} is the force experienced by the charge, qq is the charge of the particle, E\mathbf{E} is the electric field, v\mathbf{v} is the velocity of the particle, and B\mathbf{B} is the magnetic field.

Magnetic Force on a Moving Charge

The magnetic force on a moving charge is given by the cross product of the velocity and magnetic field vectors. This force is perpendicular to both the velocity and magnetic field vectors. The magnitude of the magnetic force is given by:

F=qvBsinθ{ F = qvB \sin \theta }

where θ\theta is the angle between the velocity and magnetic field vectors.

Given Values

In this problem, we are given the following values:

  • The velocity of the proton is 5.2×107m/s5.2 \times 10^7 \, \text{m/s}.
  • The magnetic field strength is 2.4T2.4 \, \text{T}.
  • The charge on a proton is 1.6×1019C1.6 \times 10^{-19} \, \text{C}.

Calculating the Magnetic Force

To calculate the magnetic force on the proton, we need to substitute the given values into the equation for the magnetic force.

First, we need to determine the angle between the velocity and magnetic field vectors. Since the magnetic field is pointing toward us and the proton is moving to the left, the angle between the velocity and magnetic field vectors is 180180^\circ. Therefore, sinθ=1\sin \theta = 1.

Next, we can substitute the given values into the equation for the magnetic force:

F=qvBsinθ{ F = qvB \sin \theta }

F=(1.6×1019C)(5.2×107m/s)(2.4T)(1){ F = (1.6 \times 10^{-19} \, \text{C})(5.2 \times 10^7 \, \text{m/s})(2.4 \, \text{T})(1) }

F=1.9328×1011N{ F = 1.9328 \times 10^{-11} \, \text{N} }

Conclusion

In this article, we have calculated the magnetic force on a proton moving at 5.2×107m/s5.2 \times 10^7 \, \text{m/s} to the left through a magnetic field of 2.4T2.4 \, \text{T} pointing toward us. The charge on a proton is 1.6×1019C1.6 \times 10^{-19} \, \text{C}. We have used the Lorentz force equation to calculate the magnetic force, and have found that the force is 1.9328×1011N1.9328 \times 10^{-11} \, \text{N}.
