Electromagnetic Force Calculator - Electric and Magnetic Forces

This physics calculator helps you calculate electromagnetic forces including Lorentz force, Coulomb force, and magnetic force. Electromagnetic forces are fundamental to understanding electricity, magnetism, and their interactions.

Electromagnetic Force Definition

• Electromagnetic Force: Force due to electric and magnetic fields
• SI Unit: Newton (N)
• Formula: F = qE + qv×B (Lorentz force)
• Nature: One of four fundamental forces

Electromagnetic Force Formulas

• Electric Force: F = qE
• Magnetic Force: F = qvBsin(θ)
• Lorentz Force: F = qE + qv×B
• Coulomb Force: F = kq₁q₂/r²
• Wire Force: F = ILBsin(θ)
• Potential Energy: U = qEd

Applications

• Electronics: Circuits and devices
• Particle Physics: Accelerators and detectors
• Medical Imaging: MRI and X-rays
• Transportation: Electric motors and generators
• Communications: Radio and television
• Energy: Power generation and transmission

Important Notes

• Electromagnetic force is a vector quantity
• Direction follows right-hand rule for magnetic force
• Electric force is independent of velocity
• Magnetic force is perpendicular to velocity
• Lorentz force combines both effects

Electromagnetic Force Types

• Electric Force: Due to electric charges
• Magnetic Force: Due to moving charges
• Lorentz Force: Combined electric and magnetic
• Coulomb Force: Between static charges
• Wire Force: On current-carrying conductors

Common Examples

• Electron Motion: In electric and magnetic fields
• Current Flow: In wires and circuits
• Particle Accelerators: Cyclotrons and synchrotrons
• Electric Motors: Force on current-carrying coils

Electromagnetic Force Units

• SI: N (Newton)
• Imperial: lbf (pound-force)
• Metric: kgf (kilogram-force)
• CGS: dyn (dyne)
• Atomic: eV/nm (electron-volt per nanometer)
