Experimental Setup

The following is Zhang Xiangqian's publicly released experimental setup, provided for reference and independent replication by qualified researchers.

Experiment 1: Accelerating Charges Generate Linear Gravitational Fields

Principle

According to the unified field theory, accelerating positive charges generate a gravitational field in the direction opposite to the acceleration. At the moment the power switch is pressed, positive charges in the conductor accelerate and vibrate in place, and the accelerating electromotive force generated between the positive and negative terminals contains a gravitational field component. Mathematically expressed as: $E_{\theta} / e_r = \vec{A} \times \vec{R} / c^2$, where $E_{\theta}$ is the distorted positive electric field, $e_r$ is the electrostatic field, $\vec{A}$ is the gravitational field, $\vec{R}$ is the position vector, and $c$ is the scalar speed of light.

Setup A: Silicone Tube High-Voltage Setup (Zhang's Original Setup)

Equipment List

Experimental Procedure

1. Insert the two insulated copper wires into the silicone tube (if difficult to insert, apply lubricant inside the tube, or use a medical syringe to inject oil). The two wires must not touch inside the tube, separated by approximately 6cm.
2. Suspend the wires and silicone tube from the wooden stand.
3. Make a 4cm × 11cm, 0.15mm thick plastic sheet, punch a hole in the center, and suspend it with thin cotton thread at the midpoint of the gap between the two wires. The sheet is sleeved over the silicone tube but must not touch it.
4. Connect the two wires to the positive and negative terminals of the 3 series-connected high-voltage modules (approximately 40,000V DC).
5. Press the power switch and observe the direction of movement of the suspended plastic sheet.
6. Reverse the polarity, repeat the experiment, and observe whether the plastic sheet still moves toward the positive terminal.

Expected Observations

• At the moment the switch is pressed, the plastic sheet moves toward the positive terminal
• After reversing polarity, the plastic sheet still moves toward the positive terminal
• The gravitational field direction is parallel to the wire, pointing from negative to positive terminal

Setup B: Field Engine No. 1 (Enhanced Version)

The thick acrylic tube plus silicone tube provides double-layer insulation, completely blocking ion wind and electrostatic motor effects from the high-voltage field, yielding a purer changing electromagnetic field gravitational effect. The two wires are disconnected inside the acrylic tube, separated by 6cm.

Experiment 2: Changing Magnetic Fields Generate Vortex Gravitational Fields

Principle

According to the unified field theory equation $\frac{d\vec{B}}{dt} = -\frac{\vec{A} \times \vec{E}}{c^2}$, a changing magnetic field not only produces an induced electric field (Faraday's law) but also generates a vortex gravitational field. This vortex gravitational field causes all objects (including non-conductors) to undergo rotational motion.

Setup A: Vacuum Chamber + High-Voltage Low-Current Setup (Most Stable)

The two coils are not connected to each other. The break points are not insulated, with an 8cm silicone tube sleeve over them (one end left open). The endpoints of the two coils are on the same plane but offset, forming a spiral-type connection in space.

Key parameters: High voltage with ultra-low current supply significantly reduces polarization effects, highlighting the vortex gravitational field effect from changing magnetic fields. This setup is relatively stable, with successful results in nearly every trial.

Setup B: Enameled Wire Coils + Post-Disconnection Rotation Setup

The two coils are attached to the top and bottom of the vacuum chamber, separated by 10cm, not connected to each other. Using thin enameled wire with many turns increases the coil inductance energy. After power disconnection, the energy stored in the coils can still cause the ball to rotate — at this point, polarization effects, electrostatic motor effects, and ion wind effects have all disappeared, leaving only the vortex gravitational field effect from the changing magnetic field, making analysis straightforward.

Setup C: Faraday Cage Verification Setup

Uses a stainless steel Faraday cage (diameter 7cm, height 18cm) with a polyethylene ball (height 5cm, diameter 2.7cm) suspended inside by thin cotton thread. One enameled wire coil (diameter 3.7cm, length 19cm, 0.57mm enameled wire) is placed on each side of the Faraday cage.

While powered, the ball inside the Faraday cage does not move (electric field is shielded). After disconnecting power and opening the Faraday cage, the ball continues to rotate. This rules out polarization effects, electrostatic motor effects, and ion wind effects — all three of these effects only exist while power is applied.

Precautions and Interference Elimination

Ion Wind Effect

In high-voltage experiments, ion wind from air ionization may push objects. Ion wind blows from the positive to the negative terminal — exactly opposite to the gravitational field effect from accelerating positive electric fields. Elimination methods: seal conductors and connectors with silicone tubes/acrylic tubes; conduct experiments in vacuum.

Polarization Effect

The polarization effect at high voltage exists even in vacuum and can penetrate thick glass. Elimination methods: use thin sheet-shaped suspended objects (suppresses polarization and depolarization effects); adopt high-voltage, ultra-low current setups; use top-bottom coil configurations so that polarization forces align with the suspension thread direction and do not contribute to rotation.

Electrostatic Motor Effect

The effect formed by positive and negative wires spraying charges or ions onto objects. Elimination methods: place electrodes outside the vacuum chamber — charges cannot be sprayed through thick glass; use Faraday cage shielding.

Important Operating Tips

• Insulation sealing: Conductors (especially connection points) must be thoroughly insulated and sealed; high-voltage modules must be covered to prevent external ion wind
• Static elimination: Preferably use a static eliminator to remove static charges from suspended objects and wiring
• Discharge residual charge: Release residual charges in the circuit before each experiment
• Avoid rapid repetition: Repeated experiments in quick succession cause severe polarization effects, turning materials into electrets and disrupting the direction of motion
• Identifying module polarity: Separate the two output wires by 8-10cm, light a candle below — the direction the flame leans toward is the negative terminal
• High-voltage module alternative: The pulsed DC output from high-voltage modules has significant noise; a pure DC high-voltage source produces better results if available

Low-Voltage Setup (80V/30A)

In addition to the high-voltage setup, Zhang Xiangqian also discovered a low-voltage approach that can observe the effect, significantly lowering the replication threshold and safety risks.
