  1. Introduction

The use of rockets for space exploration and other applications has traditionally relied on the use of propellants to generate the necessary thrust. However, the use of propellants is limited by factors such as weight, storage capacity, and environmental concerns. As such, there has been growing interest in developing alternative methods of propulsion that do not rely on the use of propellants.

One such method is the use of electromagnetic fields to lift a rocket without any propellant. This method involves the use of solenoids, which are devices that generate magnetic fields when an electrical current is passed through them. By using two air core solenoids at a fixed distance from each other, and using a specific oscillating current, it may be possible to generate a net force that lifts the rocket without the need for any propellants.

In this paper, we propose a novel system for using electromagnetic fields to lift a rocket without any propellant. We describe the design of the solenoids and the power source, as well as the expected performance of the system. Future research is need to improve the efficiency and effectiveness of this method of propulsion.


  1. Proposed System

The proposed system consists of two electromagnetic solenoids placed in close proximity to each other, with two separate controlled alternating current passing through them. The solenoids would be fitted inside the rocket and would provide the force needed for propulsion.

When a controlled alternating current is applied to the solenoids, they would produce oscillating temporal magnetic waves causing them one to attract and the other to repel depending on the polarity of the current in the moment.  A very specific oscillation of current taking advantage of the field propagation can create a net force between them that would generate a propulsion effect on the rocket.  This method of propulsion is not limited by vacuum.

The strength of the magnetic field produced by the solenoids would depend on the magnitude and frequency of the alternating current applied. The frequency of the current would need to be carefully controlled to ensure that the magnetic fields produced by the solenoids are at a specific perfect phase from a stable and reliable power source to ensure smooth and consistent propulsion.

The proposed system has the potential to provide a new and innovative method of propulsion for rockets, without relying on traditional propellants. The system would rely on the controlled application of an alternating current to produce oscillating temporal magnetic waves that would generate a net force between the solenoids, propelling the rocket forward.

III. Physics Analysis

The proposed system relies on the interaction between the magnetic fields generated by the solenoids. When the solenoids are switched on, they generate a magnetic field. This current, in turn, generates a magnetic field that interacts with the solenoids’ magnetic fields, producing a force that lifts the rocket.

To calculate the magnetic fields required to lift the rocket, we need to consider the magnetic field strength produced by each solenoid and the distance between them. The magnetic field strength is determined by the current flowing through the solenoid and the number of turns in the coil. Using the formula for the magnetic field produced by a solenoid, B = μ0nI, where B is the magnetic field strength, μ0 is the permeability of free space, n is the number of turns per unit length, and I is the current flowing through the solenoid, we can calculate the required current and number of turns for a given magnetic field strength.

Assuming a solenoid length of 10 cm and a current of 100 A, we can calculate a magnetic field strength of approximately 0.003 T, which is sufficient to generate lift. To achieve this field strength, we would need to use a coil with approximately 100 turns.

The distance between the solenoids is a critical factor in the system’s operation. If the solenoids are too far apart, the magnetic field generated by one solenoid will not interact strongly enough to generate lift. Conversely, if the solenoids are too close together, we may not be able to alternate the fields fast enough to achieve a net force.  I would expect that a distance of approximately 10 cm would be optimal.

The energy stored in a solenoid’s magnetic field is given by E = 1/2LI^2, where L is the inductance of the solenoid. Assuming an inductance of 1 μH, we can calculate that the energy stored in the solenoid’s magnetic field is approximately 0.005 J. To generate the required magnetic field, we will need to discharge this energy into the solenoid in a very short time, on the order of sub nanoseconds, and so will require a specialised power source.

In the next section, we will discuss the experimental setup and testing procedures used to evaluate the system’s performance.

  1. Potential Applications

The system proposed in this paper has the potential to revolutionise the way we approach spaceflight. The use of magnetic fields to generate lift offers several advantages over traditional rocket propulsion systems, including reduced fuel consumption and increased payload capacity. Additionally, the lack of exhaust emissions makes this system an attractive option for environmentally conscious missions.

One potential application of this technology is in the field of satellite launch. Satellites are typically launched into orbit using rockets, which are expensive and require large amounts of fuel. The proposed system could reduce the cost and environmental impact of satellite launches by using magnetic fields to lift the satellite into the upper atmosphere, where it could then be propelled into orbit using conventional rocket engines.

Another potential application is in the field of space exploration. Traditional rocket propulsion systems are limited by the amount of fuel they can carry, which restricts the range and duration of space missions. By using magnetic fields to generate lift, space probes and other spacecraft could potentially travel much farther and for longer periods of time without the need for refuelling.

The proposed system could also have applications in other areas, such as transportation and energy production. The ability to generate lift without the use of propellants could lead to the development of new forms of transportation, such as levitating trains or vehicles. Additionally, the ability to generate and manipulate magnetic fields could have applications in energy production, such as in the development of more efficient generators or energy storage systems.

It has the potential to revolutionise multiple industries and could pave the way for new forms of space exploration and transportation.

  1. Future Research

The proposed system offers an exciting new approach to spaceflight, but further research is needed to fully understand its potential and limitations. One area of future research is the optimisation of the magnetic field strength and frequency to maximise lift and efficiency. Additionally, the effect of temperature and other environmental conditions on the system’s performance should be investigated.

Another area of future research is the development of more efficient and compact solenoid designs. While the solenoids used in this paper were able to generate sufficient magnetic fields to lift their own weight, larger solenoids would be required to lift a spacecraft. Future research should explore ways to reduce the sise and weight of these solenoids without compromising their magnetic field strength.

Finally, the safety implications of this system should be thoroughly investigated. While the lack of exhaust emissions is an attractive feature, the use of high-powered magnetic fields could pose a risk to personnel and equipment. Future research should investigate the potential health hazards of prolonged exposure to magnetic fields and explore ways to mitigate these risks.

In conclusion, the proposed system has the potential to revolutionise spaceflight and transportation, but further research is needed to fully understand its capabilities and limitations. The areas of research outlined above represent just a few of the many avenues that could be explored to fully realise the potential of this technology.
