21. Explain how magnets are used on sky trains like the MagLev.
The repelling of like magnetic poles due to the reflection of the magnetic pole on the track as the train moves, allow the train to ride above the track.
Explain how magnets are used
on sky trains like the MagLev.

22. Explain how flashlights work.
Two batteries inside, current flows out the – end and into the metal on the inside of the plastic casing, switch closes the circuit so current travels to bulb lighting it.
Explain how flashlights work.
