MagneticPropulsion

Big magnets are powerful compasses which can turn our boat. Not only do the rotate the boat in Earth's magnetic field but they rotate the boat near the magnet and away from the center of mass (we maintain). So when the second servo transfers the weight of the boat away from the magnets the boat travels.

Attraction between two magnets is 1/d^3 while torque at 90 degrees between them is more like 1/d. So actually a factor of 2 greater and not as stated in the video a factor of 1. Stay tuned.

At this point this motor is limited but improvements can be envisioned such as a lipo battery instead of the 9 volt to make it lighter and faster. Stay Tuned:)

Here we get a glimpse into what is possible with Earth's magnetic field. Stay tuned:)

What lacks in torque makes up for in RPM and so we try to get the permanent magnet statorless Earth motor to turn faster and faster. Here we have used a 500 RPM n20 gear motor and get the compass motor hanging from a fishing swivel in a hoop to spin at a little over 340 RPM. At this point we will need to focus on better balance and perhaps a lower bearing. Stay tuned:)

A faster electric motor will make it go much faster as can be seen that the magnets point only slightly north east and would reach maximum torque pointing all the way east. Note the way the magnet and motor bob up and down. That is because the Earth's magnetic north is at an angle down towards the ground. Stay tuned:)

The magnets are a compass. A small electric motor turns the magnets and the armature rotates in the opposite direction. All controlled by Arduino and RCA IR remote controller. Stay tuned:)

This seems to be the point of contention with the experts on satellite design and physics students of mechanics. This is not proof but is pretty curious and not addressed anywhere that I have seen accept with some documentation for cube satellites where it is clearly stated that magnetorquers make the satellite rotate at its COM. Any comments are welcome and hoped for. Stay tuned:)

It is seen here that two of these Earth field permanent magnet statorless motors can operate near each other. There is also a large homemade compass in the foreground. They could probably be even closer together since it appears they aren't even running at the same speed here. Stay tuned:)

Some improvements to the appearance of the compass motor as well as some measurements and calculations of it's torque. Plus a mystery about stacks of magnets not getting stronger but making the motor go faster. Stay tuned:)

This compass motor is in an 8 inch hoop with a very small base and fits well in an 8 inch aluminum pan (boat) and it goes pretty well with the smaller boat and lighter motor. The motor weighs 5 3/8 Oz whereas the old version weighs 11 Oz. Stay tuned:)

In this video the Compass Motor has been modified and now has greater distance between the battery plus weight and the compass/magnet/servo. Stay tuned:)

This is the latest attempt to put the compass propulsion/magnetic propulsion in a boat that doesn't spin like crazy in the water. It seems to work but is slow because of its size and weight. But it is very promising. Stay tuned:)

In this video we see a boat made just like the Statorless Motor hanging by string with more mass on one side and rotated several turns and then stopped by the permanent magnet (compass) on a servo. This more than verifies the magnetic propulsion in Earth's magnetic field principle. Stay Tuned:)

It is seen here that placing a fixed magnet on the side of the statorless motor makes it swing and should in theory make it thrust. Stay tuned:)

Since our medium of choice for testing these magnetic propulsion devices is water we must accept that more weight means more drag and not faster speeds but perhaps faster acceleration. Stay tuned:)

Here we discuss some of the reasoning behind the magnetic boats. Stay tuned:)

The "jack knife" compass boat did 20 inches per minute after the servo was set to turn 180 degrees rather than 120 degrees to which it was set previously. Stay tuned:)

By adding 7 grams of mounting putty for weight to the heavier side of the magnetic propelled boat its speed is doubled to 10 inches per minute. Stay tuned:)

While waiting for a good explanation we will for now call this "inexpensive energy". Stay tuned:)

Putting the power of Earth's Magnetic field to work in propelling a small boat. Pretty amazing. Stay tuned:)

By replacing the servo and permanent magnet of the last version with an electromagnet we have eliminated all moving parts. (Only the entire model needs to move.) Stay tuned:)

My latest compass boat. Earth's magnetic field is immensely powerful as seen in these little magnetic propelled boats. Stay tuned:)

A tiny magnet shows just how powerful it can be. Stay tuned:)

With this version my the permanent magnet propelled boat the magnets don't need to articulate. Rather, the reaction wheel (servo and wheel) make the entire boat turn side to side. Stay tuned:)
