1. What Is The Torque On Coil Formula?

The torque on coil formula calculates the rotational force experienced by a current-carrying coil in a magnetic field. This fundamental principle is essential in understanding electromagnetic devices and their applications.

2. How Does The Calculator Work?

The calculator uses the torque on coil formula:

\[ T_d = B \times I \times N \times A \]

Where:

\( T_d \) — Torque on coil (Newton Meter)
\( B \) — Magnetic field strength (Tesla)
\( I \) — Current through the coil (Ampere)
\( N \) — Number of coil turns
\( A \) — Cross-sectional area of the coil (m²)

Explanation: The formula demonstrates how magnetic field, electric current, coil geometry, and number of turns collectively determine the torque experienced by the coil.

3. Importance Of Torque Calculation

Details: Accurate torque calculation is crucial for designing electromagnetic devices, understanding motor operations, and analyzing the performance of various electrical instruments that utilize coil mechanisms.

4. Using The Calculator

Tips: Enter magnetic field in Tesla, current in Ampere, number of coil turns, and cross-sectional area in square meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect the torque on a coil?
A: The torque depends on magnetic field strength, current magnitude, number of coil turns, and the cross-sectional area of the coil.

Q2: How does coil orientation affect torque?
A: Maximum torque occurs when the plane of the coil is parallel to the magnetic field lines. The torque becomes zero when perpendicular.

Q3: What are practical applications of this principle?
A: This principle is used in electric motors, galvanometers, ammeters, voltmeters, and various electromagnetic measuring instruments.

Q4: How does increasing coil turns affect torque?
A: Increasing the number of coil turns proportionally increases the torque, as torque is directly proportional to the number of turns.

Q5: What units should be used for accurate calculation?
A: Use Tesla for magnetic field, Ampere for current, unitless number for coil turns, and square meters for cross-sectional area to get torque in Newton Meter.
