Question
How does the electromagnetic train work?
Answer in Brief
Solution
- Electromagnets are used in Electromagnetic trains.
- Electromagnets are magnetized only when current flows through them.
- When the direction of current is changed, the poles of the electromagnets are also changed.
- Like poles of the magnets which are attached at the bottom of the train and rail track repel each other.
- So, the train is lifted from the track up to a height of 10 cm.
- We know that we can move any magnetic object with the force of attraction or repulsion properties of magnets.
- This train also moves with the help of the magnets attached on the sides of the track and the magnets fitted at the bottom sideway of the train.
- By controlling the current, we can control the magnets and movement of the train.
