磁悬浮列车想必大家都不陌生,那不仅意味着高速度,还是高科技。它利用磁性转化为了高速。我们也可以利用磁的原理来制作一艘模型船。不要把这个制作想得太复杂,更不要被吓到,其实制作也没有那么难。我们先来看看张新忠制作的磁流体动力船(见图1所示)。怎么样?还不错吧。那就让我们来看看如何制作的。首先我们需要准备如下制作材料:强磁铁7块(30mm×25mm×4mm)、石墨电极8块、塑料船体一艘、遥控汽车控制电路一套、继电器4 Maglev train must be familiar to everyone, it means not only high-speed, or high-tech. It uses magnetism for high speed. We can also use the principle of magnetism to make a model boat. Do not think of this production too complicated, not to be scared, in fact, production is not so difficult. Let’s take a look at the magnetohydrodynamic craft made by Zhang Xinzhong (see Figure 1). How’s it going? Then let’s see how to make it. First, we need to prepare the following materials: strong magnet 7 (30mm × 25mm × 4mm), graphite electrode 8, a plastic hull, a remote control car control circuit, the relay 4
