Introduction

The interaction between electric charge, magnetic field, and force is a fundamental concept in physics that has numerous applications in various fields, including engineering, technology, and research. In this article, we will delve into the specifics of a problem involving a charge moving at an angle to a magnetic field, and explore the underlying principles that govern the resulting force.

The Problem

A charge of $8.4 \times 10^{-4} , C$ moves at an angle of $35^{\circ}$ to a magnetic field that has a field strength of $6.7 \times 10^{-3} , T$. If the magnetic force is $3.5 \times 10^{-2} , N$, what can we infer about the direction and magnitude of the force?

The Lorentz Force Equation

The Lorentz force equation is a fundamental concept in physics that describes the interaction between electric charge, magnetic field, and force. The equation is given by:

F⃗=q(E⃗+v⃗×B⃗)\vec{F} = q(\vec{E} + \vec{v} \times \vec{B})

where $\vec{F}$ is the force experienced by the charge, $q$ is the magnitude of the charge, $\vec{E}$ is the electric field, $\vec{v}$ is the velocity of the charge, and $\vec{B}$ is the magnetic field.

The Magnetic Force Component

In this problem, we are only concerned with the magnetic force component, which is given by:

FB⃗=q(v⃗×B⃗)\vec{F_B} = q(\vec{v} \times \vec{B})

The magnitude of the magnetic force is given by:

FB=qvBsin⁑θF_B = qvB\sin\theta

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

Calculating the Magnetic Force

We can now calculate the magnetic force using the given values:

FB=(8.4Γ—10βˆ’4 C)(v)(6.7Γ—10βˆ’3 T)sin⁑(35∘)F_B = (8.4 \times 10^{-4} \, C)(v)(6.7 \times 10^{-3} \, T)\sin(35^{\circ})

To find the velocity, we can use the given magnetic force:

3.5Γ—10βˆ’2 N=(8.4Γ—10βˆ’4 C)(v)(6.7Γ—10βˆ’3 T)sin⁑(35∘)3.5 \times 10^{-2} \, N = (8.4 \times 10^{-4} \, C)(v)(6.7 \times 10^{-3} \, T)\sin(35^{\circ})

Solving for $v$, we get:

v=3.5Γ—10βˆ’2 N(8.4Γ—10βˆ’4 C)(6.7Γ—10βˆ’3 T)sin⁑(35∘)v = \frac{3.5 \times 10^{-2} \, N}{(8.4 \times 10^{-4} \, C)(6.7 \times 10^{-3} \, T)\sin(35^{\circ})}

Evaluating the Velocity

Evaluating the expression for $v$, we get:

v=3.5Γ—10βˆ’2 N(8.4Γ—10βˆ’4 C)(6.7Γ—10βˆ’3 T)sin⁑(35∘)=1.23Γ—102 m/sv = \frac{3.5 \times 10^{-2} \, N}{(8.4 \times 10^{-4} \, C)(6.7 \times 10^{-3} \, T)\sin(35^{\circ})} = 1.23 \times 10^{2} \, m/s

Calculating the Magnetic Force

Now that we have the velocity, we can calculate the magnetic force:

FB=(8.4Γ—10βˆ’4 C)(1.23Γ—102 m/s)(6.7Γ—10βˆ’3 T)sin⁑(35∘)F_B = (8.4 \times 10^{-4} \, C)(1.23 \times 10^{2} \, m/s)(6.7 \times 10^{-3} \, T)\sin(35^{\circ})

Evaluating the expression, we get:

FB=3.5Γ—10βˆ’2 NF_B = 3.5 \times 10^{-2} \, N

Conclusion

In this article, we explored the interaction between electric charge, magnetic field, and force using the Lorentz force equation. We calculated the magnetic force experienced by a charge moving at an angle to a magnetic field, and found that the force is given by:

FB=qvBsin⁑θF_B = qvB\sin\theta

We also evaluated the velocity of the charge and calculated the magnetic force using the given values. The results show that the magnetic force is $3.5 \times 10^{-2} , N$, which is consistent with the given value.
