看过《黑客帝国》的人应该知道，电影中飞船需要不断接触周围的岩石产生磁场，来控制加速、转向等操作，它其实用的就是核动电磁力。
也可以用电磁力啊，但它有一个前提，那就是像磁悬浮高铁一样需要一条专门的电磁轨道，对于自由行驶的汽车而言，这是不现实的。《黑客帝国》中其实还有一种更高级的动力，机械大乌贼就是利用这种力飞行，我们姑且称之为" 反重力 "，在很多科幻片中都有提到，也就是除自然界已发现的电磁力、万有引力、强力和弱力四种基本作用力之外的 " 第五种力 "。
只是以人类目前的科技水平，还抓不住这么虚无缥缈的东西。相比之下更可靠的方案可能是离子发动机，原理就是利用电力将气体电离，然后用电场将带电离子加速喷出来产生推力。
English version
Those who have seen "The Matrix" should know that the spacecraft in the movie needs constant contact with the surrounding rocks to generate magnetic fields to control acceleration, steering, etc. Its practical use is to mobilize electromagnetic forces.
Electromagnetic force can also be used, but it has a premise that it requires a special electromagnetic track like a magnetic suspension high-speed rail. This is unrealistic for a free-running car. There is actually a more advanced power in "The Matrix". The mechanical squid is flying with this force. Let's call it "anti-gravity". It is mentioned in many science fiction films, that is, except for nature. The "fifth force" other than the four basic forces of electromagnetic force, gravitation, strength and weakness.
It’s just that people’s current level of technology can’t catch such illusory things. In contrast, a more reliable solution may be an ion engine, the principle is to use electricity to ionize the gas, and then use the electric field to accelerate the jet of charged ions to generate thrust.
