1. What Are The Units Of Magnetic Force?

Definition: The magnetic force on a moving charge is measured in Newtons (N), the SI unit of force.

Purpose: Understanding magnetic force units is essential in physics and engineering applications involving electromagnetism.

2. How Is Magnetic Force Calculated?

The calculator uses the formula:

\[ F = qvB \sinθ \]

Where:

\( F \) — Magnetic force (Newtons)
\( q \) — Electric charge (Coulombs)
\( v \) — Velocity of charge (meters/second)
\( B \) — Magnetic field strength (Tesla)
\( θ \) — Angle between velocity and field (degrees)

Explanation: The force is proportional to the charge, velocity, field strength, and the sine of the angle between them.

3. Importance of Magnetic Force Calculation

Details: Accurate force calculation is crucial for designing electric motors, particle accelerators, and other electromagnetic devices.

4. Using the Calculator

Tips: Enter the charge in Coulombs, velocity in m/s, magnetic field in Tesla, and angle in degrees (90° for maximum force).

5. Frequently Asked Questions (FAQ)

Q1: Why are Newtons used for magnetic force?
A: Newtons are the SI unit for all forces, including magnetic, electric, and mechanical forces.

Q2: What's the difference between Tesla and Newton?
A: Tesla measures magnetic field strength, while Newton measures the resulting force on a moving charge.

Q3: How does angle affect magnetic force?
A: Force is maximum at 90° and zero at 0° (parallel motion). The force varies with the sine of the angle.

Q4: What's a typical magnetic field strength?
A: Earth's field is ~50 μT, refrigerator magnets ~5 mT, MRI machines 1-3 T.

Q5: Can this calculator be used for current-carrying wires?
A: Yes, by using qv = IL (current × length) in the formula.
