Magnetic Pressure Calculator

1. What is a Magnetic Pressure Calculator?

Definition: This calculator computes the magnetic pressure (\( P_m \)) in a magnetic field based on the formula \( P_m = \frac{B^2}{2 \mu_0} \), where \( B \) is the magnetic field strength and \( \mu_0 \) is the magnetic permeability of free space (\( 4\pi \times 10^{-7} \) H/m).

Purpose: It helps physicists, engineers, and scientists analyze magnetic forces in applications like plasma physics, magnetic confinement fusion, and electromagnetism, particularly for understanding pressure exerted by magnetic fields.

2. How Does the Calculator Work?

Calculations are based on the magnetic pressure formula:

\[ P_m = \frac{B^2}{2 \mu_0} \]

Unit Conversions:

Category Unit Conversion to SI Unit
Magnetic Pressure Pa (Pascals) 1 Pa
bar 1 bar = 100,000 Pa
psi (Pounds per square inch) 1 psi = 6894.76 Pa
at (Technical atmospheres) 1 at = 98,066.5 Pa
atm (Standard atmospheres) 1 atm = 101,325 Pa
Torr 1 Torr = 133.322 Pa
hPa (Hectopascals) 1 hPa = 100 Pa
kPa (Kilopascals) 1 kPa = 1000 Pa
MPa (Megapascals) 1 MPa = 1,000,000 Pa
inHg (Inches of mercury) 1 inHg = 3386.39 Pa
Magnetic Field (B) uT (Microteslas) 1 uT = 10⁻⁶ T
mT (Milliteslas) 1 mT = 10⁻³ T
T (Teslas) 1 T
GT (Gigateslas) 1 GT = 10⁹ T
G (Gauss) 1 G = 0.0001 T
Explanation: Magnetic field strength is converted to Teslas (SI unit), and magnetic pressure is calculated in Pascals, then converted to other units.

3. Importance of Magnetic Pressure Calculation

Details: Accurate magnetic pressure calculations are crucial for understanding the forces exerted by magnetic fields in plasma physics, fusion reactors, and electromagnetic devices, ensuring proper design and operation in scientific and engineering applications.

4. Using the Calculator

Tips: Enter Magnetic Field (uT, mT, T, GT, G). Results include magnetic pressure in multiple units (Pa, bar, psi, at, atm, Torr, hPa, kPa, MPa, inHg).

5. Notes

Notes: Magnetic pressure is the pressure exerted by a magnetic field on a medium, particularly in plasmas or ferromagnetic materials. The magnetic permeability of free space (\( \mu_0 \)) is fixed at \( 4\pi \times 10^{-7} \) H/m, and the magnetic field strength must be positive.
