Model Maglev Train starting motor help

AI Thread Summary
A high school student is designing a model maglev train based on the Inductrack concept, using permanent magnets and a simple coil track. The cart will initially have wheels for movement until it reaches 1-2 km/h, at which point it will levitate due to electromagnetic repulsion from the coils. The student seeks assistance in selecting a motor to achieve the necessary speed and is curious if a strong enough battery could create an immediate electromagnetic field for levitation. They are considering building the system at an angle to utilize gravity for propulsion once levitation is achieved. The discussion emphasizes the need for effective motor solutions and battery specifications for successful operation.

OKay i am a high school student making a model maglev train like the Inductrack design.

I haven't started building yet but i know how I am going to make it and since i am using permanent magnets, the cart will not levitate right away. It will have wheels on the sides of the cart on rails to rest on. When the cart starts to move at 1-2km / hr the cart will leviate and won't need the wheels. What i need is ideas and help on making a motor to get that cart moving at 1-2 km / hr. HELP!

the cart will be a wooden plank with magnets in a row length wise on either side of the bottom of the cart forming an "L" sideways with another row as guidelines on the outside (rows are halbach arrays) the track is simple coils of wire (with two rails for the wheels)

as the cart starts to move due to the motor at a certain speed an electromagnetic field from the coiled wire will repel that of the cart, thus levitation. the cart will look like this:

_____wood____
|-...-| <-- magnets track like this:

________
|_______| in middle probably wood or something
^
|
wire
SO I NEED A MOTOR long story short.
please help!
 
Physics news on Phys.org
really, no one knows? :( just a motor or even something to get it moving.

i forgot to mention that the coiled wire will be attached to a battery source to create the electromagnetic field. like a circuit. does anyone knoe that if i use a strong enough battery will it repel the cart up straight from the get go?

if it does i can build it on an angle so i when i use a switch to complete the circuit of the battery and coiled wire, it repels and thus levitates the cart, and gravity will do the propulsion for me! please help with a motor r can someone let me know if i can create a strong enough electromagnetic field form a strong enough battery to repel the cart right away?

thanks
 
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
