I found a dead bee on my front porch and went to pick it up with some tweezers. Before I even touched it, the bee moved slightly. I raised my hand and the bee followed the tweezers just staying suspended as if hanging by a cobweb. But no cobweb. So I tested further. The ass end is magnetic. This is weird. The ass end and the body are detatched yet still attached by static electricity. (Non-Contact Attachment) I unbent a paper clip and put it near the bee shell and I could move the shell around without touching it. Only dragging it though. I separated the ass end from the body ever so slightly just to make sure they weren't attached and they snapped back together like 2 magnets. I dangled this dead bee from what seems like static electricity. There are some magnetic anomalies near bee hives. I don't think a bee hive registers on a gauss meter either. A compass will deviate from North the closer to the hive you get. Neodymium magnets seem to have no affect on the bees. The slightest shift in magnetism = the slightest shift in gravity. Gravity = time. With enough bees placed in a specific fractal orientation, perhaps a vortex can be created where gravity / time is altered slightly or even drastically. The bee in this video is NOT attached by a spider web, piece of string, or anything. Chitin is what all insects are made out of. Chitin is diamagnetic which means it repels magnetism.

More stuff like that at or http**Teslameter**Teslameter A teslameter is a device (magnetometer) used to measure magnetic inductance or magnetic field strength in a non-ferromagnetic medium. The device was named after Tesla - a magnetic inductance unit in the International System of Units. Initially the most widespread version of a teslameter was based on the induction principle and consisted of an inductance converter (coil) and an electric meter. In measuring interlinkage of an inductance converter and magnetic field the inductance of which is to be determined, the converter generates the electromotive force measured by the device. In magnetostatic fields the interlinkage changes as a result of movements of inductance converter (linear translation, rotation, vibration, etc.); whereas in the alternating magnetic fields that happens due to changes in the value and direction of the field. In the case of static fields the values are measured with the help of a webermeter (flux meter), and in the case of the alternating ones - with the help of voltmeters, oscilloscopes, etc. Apart from the inductance telsameters, there are also fluxgate teslameters and Hall probe teslameters. The latter can be easily built as an add-on to multimeter that consists of a Hall probe and a voltage supply regulator. When the magnetic field changes, so does the probe's output voltage supplied to the multimeter input. Teslameters are used to measure the electromagnetic field of power lines, household appliances and industrial devices.

A large lifter magnet (not visible) attracts the tiny 1x1x1mm NdFeB N52 cube magnet. At this small scale and due the field geometry of the larger lifter magnet the weak diamagnetism of copper is sufficient for holding the tiny cube magnet in a stable levitation position. Be aware that this is not an eddy current levitation but diamagnetically stabilized levitation. The levitation is free and stable and needs no energy input. What you can see is of course eddy current damping when one trys to misalign the floating magnet. The levitation height is only about 0.3 mm. The match head is for size comparison.

FEMM is a GNU license piece of software from David Meeker and you can get it from It's pretty easy to use for basic modelling but there does seem to be quite a learning curve for anything more complex. Still, it did what i wanted. The model is 12cm by 10 cm and shows a laminated steel frame with four coils placed central to each leg of the fram and two N50 magnets either side of the top and bottom coils. To start with i pulsed 1 amp at 8 volts through each of the top and bottom coils as per the standard flynn device, which is a power consumption of 16 watts, and the flux movement was pretty much as you would have thought. But it got interesting when i pulsed the left hand side coil only. I could get this down to a 0.5 amp pulse at 4 volts to achieve the same effect as the 16 watts version but with only 2 watts of power consumption. This seemed pretty interesting so i decided to reverse the pulse through the left hand coil with the result that you can see. The next step - build the thing!

Applications discussed include magnetic levitation, magnetic shielding, coupled stress and magnetostatic ***ysis applied to superconductors, Type I and Type II superconductors, and superconducting flux focusers.

This tutorial shows the abilities found in EMS to solve electrostatic problems coupled with thermal ***ysis. The subjects of interest are the electric field distribution and the temperature distribution of this insulator. The first half of the tutorial focuses on the input and preprocessing phase. Using the powerful EMS CAE solution fully embeded in Solidworks, electromagnetic and mechatronics field simulation of the most complex electromechanical designs has never been this easy!
