Abstract: This paper proposes a novel hypothesis linking the Earth's 26-second microseismic pulse to magnetic torque-induced rotational jerks of the Earth's solid inner core. Contrary to the conventional view of smooth differential rotation, we suggest that the magnetic coupling between the liquid outer core and the solid inner core produces periodic angular jerks of approximately 0.108333 degrees every 26 seconds. This accumulates to a full 360-degree rotation in 24 hours. This mechanism may explain both the Earth's hum and anomalies in core dynamics.

  This hypothesis can resolve few long unanswered questions like

1) Why Microseisms ( Earth Pulse/Beat) every 26th Second
2) Why Earth core speed ,sometimes ,differ to Earth rotation
3) Why some times ,Earth core lead in rotation by 0.1 degrees over hundreds of years( When magnetic drag exceeds ,it over shoots the core and hence can take lead)

1. Introduction The Earth exhibits a persistent microseismic oscillation every 26 seconds, commonly known as the Earth's hum. Traditional interpretations attribute this to ocean wave resonance or atmospheric turbulence. Meanwhile, seismological studies suggest that the inner core may rotate at a slightly different rate from the mantle. This paper explores the possibility that the Earth's hum originates from quantized magnetic torques acting on the solid inner core.

2. Background

2.1. Earth's Core Structure:

Inner Core: Solid, radius ~1220 km, composed primarily of iron-nickel.

Outer Core: Liquid, electrically conductive, source of geomagnetic field via dynamo effect.


2.2. Magnetic Coupling:

Differential motion of conductive layers induces Lorentz forces.

Magnetic field lines exert torque across the inner core boundary.

Prior estimates show magnetic coupling is stronger than viscous effects but weak in instantaneous acceleration.


2.3. The 26-Second Microseism:

Observed worldwide.

Source not definitively established.

3. Hypothesis Statement We hypothesize that magnetic coupling between the outer and inner core builds torque gradually, and when it reaches a threshold, it triggers a discrete angular jerk of 0.108333 degrees every 26 seconds. Over 24 hours, this results in a full 360-degree rotation:

 

This quantized motion could explain the observed 26-second signal as a geophysical response to internal torque release.

4. Supporting Physics

4.1. Torque Calculation: Estimated torque required to rotate the inner core to Earth-like angular velocity:

4.2. Torque per Unit Area: Inner core surface area: 

4.3. Magnetic Torque: Using estimated field strength and coupling models:

These values are sufficient over time to induce minor rotational steps.

5. Predictions and Observables

Inner core rotational anomalies should correlate with geomagnetic fluctuations.

Seismic anisotropy or scattering may reflect these periodic changes.

Artificial gyroscopic satellites could detect pulse-consistent variations in Earth's moment of inertia.

6. Future Work

Vacuum-based Foucault pendulum experiments.

Long-term magnetometer and seismometer correlation studies.

Numerical simulation of torque buildup and threshold release dynamics.

7. Conclusion This hypothesis presents a physically grounded mechanism to link Earth's magnetic field dynamics with observed 26-second microseisms. The idea that the inner core rotates via discrete magnetic jerks opens a new line of investigation into Earth's deep interior processes.
