Asalam alykum warahmatullahi wabaraktuh,

one of my friends has developed a great idea,he wants to apply it for patent,yet the people asked him for more clear details and his idea was kind stolen by a great company nearby,they have the money to do so,you know the real life,
now

i want to know are there any ideas known with magnetic cars ?

very appreciate for your contribution.

magnetic levitation for cars has been thought of over 30 years ago. Your friend isnt on to anything new, even the movie Back to the Future 2 featured Magnetic Levitation in cars.

magnetic trapping ? that idea has been around for ages and no its not feasible enough for levitating cars however reducing friction for high speed train system has found it useful to implement the idea..It is being researched and implemented by a university in Taiwan i believe, there may be other research fronts as well

I myself have few details about his idea,but it is something else as this,because he is electrician and he has ideas of saving ressources by gaining great power with less energy.

The company i think wanted him to sell this idea to them,yet he refuses.

I haven't heard of cars which use magnetic lavitation but I have seen trains in Shanghai China using magnetic lavitation.

I haven't heared yet news from him,but he is further researching great ideas,using magnetics,i do myself have also ideas which i can freely present here :

like avoiding crashes between vehicles using eletrical magnetics...maybe i will show next time an image.InshaAllah.

It's impossible for several reasons.

1) There are more than 2 cars on this planet.

It's easy to make 2 magnets repel each others.

But in a situation where 3 magnets are involved, your idea is not possible.

2) I assume the goal of this device would be to save the passenger's life.

But it will only prevent the cars from crashing.

You still have to dissipate the kinetic energy stored by your body.

In other words, it will stop your car but not you, you will crash in the windshield.

3) It requires way too much energy to create a relevant magnetic field.

Electromagnets can lift a motionless car but it requires hundreds of Amperes.

Now imagine if a car has a high velocity.

Brother Al Hanif,is verily a mathematician

i know myself these,and especially the difficulties.

I think to avoid accidents you need common sense more than magnets under the road

In cybernetics you work with robots and other innovations about changes and how to confront them,its amazing....like if there is wind from one side on a car,how can the automatic system help the driver to control the car.
