Lorentz Force Calculator
What is Lorentz Force?
The Lorentz force is the force experienced by a charged particle when it moves through electric and magnetic fields. It is a fundamental concept in electromagnetism and plays a key role in physics, electrical engineering, and modern technology.
The magnetic part of the Lorentz force is given by:
F = q × v × B
Where F is force (Newton), q is charge (Coulomb), v is velocity (m/s), and B is magnetic field strength (Tesla).
Understanding Lorentz Force
When a charged particle moves in a magnetic field, it experiences a force perpendicular to both its velocity and the magnetic field direction. This results in circular or helical motion of the particle.
The direction of the Lorentz force can be determined using the right-hand rule. If the charge is positive, the force follows the rule directly. If the charge is negative, the direction reverses.
This force is responsible for many real-world phenomena such as:
- Motion of electrons in magnetic fields
- Operation of electric motors
- Particle acceleration in cyclotrons
- Behavior of charged particles in space
In practical applications, Lorentz force is used in devices like mass spectrometers, magnetic confinement systems, and sensors. It is also essential in understanding plasma physics and astrophysics.
How to Use the Calculator
- Enter any three values among Force (F), Charge (q), Velocity (v), and Magnetic Field (B).
- Leave one field empty.
- Click the Calculate button.
The calculator will compute the missing value using the formula F = qvB.
Example Calculation
If:
- q = 2 C
- v = 5 m/s
- B = 1 T
Then:
F = 2 × 5 × 1 = 10 N
This calculator simplifies electromagnetic calculations and ensures accurate results without manual effort.
