by

Introduction

Inductance is a fundamental property of electrical circuits, representing the ability of a conductor to store energy in a magnetic field. Understanding and converting between different units of inductance is crucial for engineers, physicists, and students working in electromagnetism. In this article, we will explore the quick and accurate conversion of 39.8 Petahenry (PH) to 3.98 × 10²⁵ Electromagnetic Units (EMU) of inductance, explaining the concepts, formulas, and steps involved.

Inductance Units

What is Inductance?

Inductance (L) is measured in Henrys (H) and describes how much voltage is induced in a conductor when the current changes. Larger values of inductance require Petahenry (PH) and EMU (Electromagnetic Units) for practical representation.

Common Inductance Units:

  1. Henry (H) – The SI unit of inductance.
  2. Petahenry (PH) – 1 PH = 10¹⁵ H (used for extremely large inductances).
  3. EMU of Inductance – Part of the Centimeter-Gram-Second (CGS) system, where 1 EMU = 10⁻⁹ H.

Conversion Formula: PH to EMU

To convert Petahenry (PH) to EMU of inductance, use the following relationship:1 PH=1015 H1PH=1015H1 H=109 EMU1H=109EMU

Thus,1 PH=1015×109 EMU=1024 EMU1PH=1015×109EMU=1024EMU

Step-by-Step Conversion of 39.8 PH to EMU

  1. Convert PH to Henry (H):39.8 PH=39.8×1015 H39.8PH=39.8×1015H
  2. Convert Henry (H) to EMU:39.8×1015 H=39.8×1015×109 EMU39.8×1015H=39.8×1015×109EMU=39.8×1024 EMU=39.8×1024EMU=3.98×1025 EMU=3.98×1025EMU

Final Result:39.8 PH=3.98×1025 EMU39.8PH=3.98×1025EMU​

Why is This Conversion Important?

  • Scientific Research: Large inductance values are common in superconducting magnets and astrophysical studies.
  • Engineering Applications: High-energy physics and magnetic resonance imaging (MRI) systems use such conversions.
  • Education: Students must understand unit conversions for electromagnetism problems.

Common Mistakes to Avoid

  1. Misplacing the exponent: Ensure correct powers of 10 when converting between PH and EMU.
  2. Confusing EMU with ESU: EMU (Electromagnetic Units) and ESU (Electrostatic Units) are different.
  3. Ignoring unit consistency: Always verify dimensions in equations.

Frequently Asked Questions (FAQs)

1. What is the difference between PH and EMU of inductance?

  • PH (Petahenry) is an SI unit (1 PH = 10¹⁵ H).
  • EMU is a CGS unit (1 EMU = 10⁻⁹ H).

2. How do I convert EMU back to PH?

Use the inverse relation:1 EMU=10−9 H1EMU=10−9H1 PH=1024 EMU1PH=1024EMU

3. Where is EMU inductance used?

EMU is common in theoretical physics and older scientific literature using the CGS system.
