Vizimag, a magnetic simulation program was used to simulate the Inductrack theory. A five magnet
Halbach array is seen in figure 1.
Figure 1 - Simulated Halbach Array Magnetic Fields
When the Halbach array passes over the track, current is induced. The current induced in the track creates
a magnetic field. This magnetic field creates drag forces shown in figure 2.
Figure 2 - 0 Degree Current Lag Simulation
As the velocity of the Halbach array increases, the induced current begins to lag, or be delayed.
Figure 3 shows the induced current lagging 45 degrees (-45 phase lag). It can be seen that the
magnetic fields begin to create a vertical levitating force as the horizontal drag force decreases.
Figure 3 - 45 Degree Current Lag Simulation
As the velocity of the Halbach array keeps increasing, the induced current lag approaches 90 degrees.
The magnetic poles of the Halbach array line up with like-poles of the induced magnetic fields.
The magnetic fields create levitation forces with nearly no drag forces. This can be seen in figure 4.
Figure 4 - 90 Degree Current Lag Simulation
An animated version of the magnetic field simulations is shown in figure 5. This figure simulates
the Halbach's velocity speeding up and slowing down.
